So he changes from a weak, gut-reaction-based townread to a scum read. It's not like he was hard defending zboson or even really thinking about it in a way that we should be super concerned about, he was just pooping ideas out onto the thread. So, if his reasoning for the original town read was bad, then why did he state it if he is town? You don't just say, 'oh, this guy is town, but I have bad reasoning for it' if you're town. So, he must've thought his reasoning was good outright state it....gimme a sec to organize a whole post on his vote | ||

Town read on Z-Bo + Show Spoiler + On November 13 2012 09:50 iamperfection wrote: zbos explained it in his post would have been very risky in my view. On November 13 2012 09:55 iamperfection wrote: its what i think so whatever. Zbos scum is gone put himself out there like that i dont think so. Alright, these two posts seem pretty strong saying that Z-Bo is townie. Note the word use "very risky for scum" and "scum wouldn't put themselves out there like that" On November 13 2012 10:33 iamperfection wrote: guys a town zbos could lie if he was blue He could be scum he could be vt. I'm inclined looking at the comment that he was just writing what he thought and that it was probably true. He just had a slip of the tongue so i'm actually inclined to think it was actually the truth. It didn't look like to me as a scum making a post in order to put a claim together. Boom i got two town reads already which you gonna do mafia?????????? Here he states outright that he has a town read on Z-Bo Note that his town read is a null tell to me. Suspicions of BH ----> Agreeing with BH Next, iamp becomes suspicious of BH + Show Spoiler + On November 13 2012 11:31 iamperfection wrote: so uh this guys is like not helping right now and i expect better from him since i hold him in high regards. i say we force his hand. ## Vote Blazinghand Especially since he made it obvious that he was here with his "lol" Note the timestamp. 30 minutes later, this comes out On November 14 2012 00:04 iamperfection wrote: LOL dont you dare talk down to me you little punk. You criticize me when YOU were the one being all terrible with your first couple of posts. Being all herp derp i don't have to contribute even though interesting things were happening at the time. Give me a break But that being said ## Unvote Your case on zbos reminds me more of your play from rockband more then the way you were being early on. Lokking at what zbos has posted especially this crap which bh pointed out If you look closely debears never said anything about being able to tell if marv is town or not from an anyltical standpoint he made it pretty clear that it was not the case and that he had said he was simply going to vote for him no matter what. Zbos totally misrepresents what is being said here and if he has the courage to throw a vote out for it you would have thought he would have read clearly what he was in fact voting for. This post here is also another pile of crap and its the iamperfection rule of whoever defends me is probably scum. If he cared at all to check in gsl III where i was scum which he played in lollololol i thrw around 2 strong town reads early on he should know this and the fact that he isnt willing to do any legwork in order to find out is more evidence not in his favor. This post is also extremly wishy washy on everything he said. I know i said early on that i thought the miller claim was more of a town tell but well i think zbos actions speak louder. so ## Vote zboson Note the two changes here 1) BH is suddenly town because of one case 30 minutes after iamp's original suspicion 2) Z-Bo is suddenly scum because of BH's case Note his poor reasoning. His first point is BH's reasoning. His second point is the "imperfection rule"...Really??????? Also, remember that it was and is the first half of d1 at this point. Why is he jumping on Z-Bo for two fucking posts? Why is he jumping on a case from a person whom he thought was suspicious 30 minutes prior? See how poor that reasoning is? When you switch from a town read to a scum read, you're reasoning should be pretty good. An apparent guilty conscience I know i said early on that i thought the miller claim was more of a town tell but well i think zbos actions speak louder. Ok. What does this line from his vote post on Z-Bo tell us about iamp? 1) He cares about how the town is viewing him 2) He doesn't believe his reasoning is that great for his vote -note the "well I think his actions speak louder". It's a weak statement. Not a strong one, (a strong one) which should be warranted when you change your read from town to scum in literally no time Point 1 is a null tell. Point 2 doesn't make any sense from a townie perspective. What are your guy's thoughts??? | ||

1) He turned from a town read to a scum read and vote with poor reasoning. That's scummy as shit 2) Let me ask you this. Why would town iamp do it? A town player does not suddenly vote based on bad reasoning, let alone swap from town to scum read. Why would scum iamp do it? Because scum knows their reasoning is not true. They are looking for scumminess in people who are town. Also, I would like to offer a counter thought to my assumption that he thought his reasoning was bad 1) He thinks his reasoning is good 2) He has a sudden change of a opinion to agree with his suspicion (BH) from 30 minutes before. 3) He makes a weak "oh nvm about the town tell" statement Why does he go out of his way to state that at the end of his post if he thinks his reasoning is good? | ||

The only time I purposely avoided posting in mafia was my last game when Alsn said that he would take his vote off my scumbuddy if I didn't show up. You weren't my top scumread. Hopeless was and still is. It's hard to make a better case/more arguments when he fails to post much. I was going after you because your fucking flip flop had 0 townie reasoning for it when you had seen BH as suspcious 30 minutes earlier. And guess what? Multiple people agreed with me | ||

He jumps on Hopeless really quickly, who's one of the easier targets in the game. He's then pretty quick to jump on iamperfection, and has been pushing that "read" since. As previously stated, his "vote post" looks like an overkill-case. But the thing that really sticks out to me is that he's been tunneling iamperfection for the last few hours yet still has his vote on Hopeless. He's using a lot of strong language against iamperfection (much stronger than against hopeless), and from his filter it looks like iamperfection is his top scumread. At this point he's much more content to push the read on iamperfection than his one on Hopeless, and I see no townie reason why his vote isn't where his mouth is. ##Unvote ##Vote debears If you look at my posting before the iamp stuff, I was focused on Hopeless. However, Hopeless failed to post much after that, and he still has. I feel like his lecturing + lack of posting is much more scum indicative than iamp's posting, hence my vote on hopeless and not iamp And about the one liners. It was the first 14-18 hours of d1. Not much to go off of for big cases, especially with thrawn, dp, hopeless, kickstart, and crossfire contributing minimally. Wow that's 5/13 players. Hey thats more than 1/3 of the game!!!!!!!!!!!! Amazing Hapa, why are you focusing me over the above stated 5 players? Also Hapa, why are you attacking easy targets: S&B, Kickstart, Me(after i go afk). What happened to your iamp scum read hapa?

Making a 180 when spurred by another case is scummy and convenient. I realize you disagree, but I think you're wrong. And to draw comparisons to the read on Kei you mentioned in GSL III - I find imaperfection's actions alone much more scummy than Kei's actions in GSL III. Kei has a history of reluctant D1 play. Iamperfection doesn't have a history of these things in his town play to my knowledge. to On November 14 2012 08:39 Hapahauli wrote: @iamp ##Unvote From your reactions so far, you're probably town. The "I don't give a fuck" thing has been on full display for the last few hours, and that meta read hasn't been wrong on you yet. I also do like the post on Z-Bo, but I give him less townie points than you do. Z-Bo can push a read as either allignment, but I do agree he's being open so far. I see that you override his in game play with meta on d1. Very interesting | ||

Yes I am playing badly. Yes I have excuses which are valid. If you lynch me it is a mislynch. I feel I could genuinely contribute to the game when I have more time. But I can understand where you are coming from also. Please just ask why on earth I would play scum this way when I could easily tunnel some lynch bait. DP have you read the thread fully yet?

/fireball debears Let's take a look at my top scumread for most of d1, Hopeless http://www.teamliquid.net/forum/viewmessage.php?topic_id=381440&user=123725 Here's his filter link. There's not much in it. A bunch of one-liners with a couple of longer posts focused on my crossfire smurf/hapa discussion. What has Hopeless done to make me think he is town? Absolutely nothing. He didn't vote me, yet half his filter is about me. He dropped his "pressure" on me pretty quickly. What has Hopless done to make me think he is scum? He came out lecturing town in one of his first posts here On November 13 2012 10:50 Hopeless1der wrote: trying their best? doubtful so far. DP's been voted for rolling too much scum. Marv was voted because of some kind of promise. Hapa was voted for. SnB was voted for being 'retarded'. real Try-Hard material right there. What had Hopeless done up to this point? Absolutely nothing. Why does he feel the need to lecture town? Because he has nothing to contribute And honestly, there is nothing else to say on him still, cuz his posting is void of content | ||

Alright guys, I really need someone to give me a good answer on this question, which everyone has failed to do Why would town iamp 1) Switch his vote, agreeing with the case of someone he thought was scummy 30 minutes earlier after 1 case? 2) Switch his vote onto someone who he said was town earlier in the game? Let's look at iamp's scumhunting so far: Z-Bo. That's it. And guess what? His new scumread is me. Why?? On November 14 2012 10:19 iamperfection wrote: i might be able to get behind this but i will wait for him to respond. Looking at it your absolutely right because i had to double check i could have sworn his vote was on me but it in fact isn't. He did use strong language but didnt put the vote out there and was curios to see what others thought (Testing the waters maybe?) however i will wait for him to respond. This is the first mention of my scumminess the whole game. Why the sudden change? "I didn't realize he didn't have his vote on me". Really? I was making arguments against you and you aren't reading them then? Is that what is going on? Is that your only reason for wanting to vote me (oh and you haven't anyways)? This is what he says for other reasoning On November 14 2012 13:14 iamperfection wrote: well i think the obvious question is whats the deal with not having a 10 page filter by now? oh also your tunneling on me looks bad now because almost everyone thinks im town now.

I never said iamp was my top scumread. Now you're just grasping for straws on a fucking retarded assumption. You don't even realize that my top scumread wasn't and still hasn't been active or cared about the town/game when my vote was still on him. I can push whoever I want when I see it beneficial to do so. Iamp here are some questions for you. Answer them 1) Did you think you're reasoning on Z-Bo was strong? If so, 1. Why did you make a sudden 180 on your town read on his miller claim, especially that early d1? 2. Why did you go out of your way to point out your town read on him earlier with a weak "I guess so" statement if you thought you had a good case? 2) If not: Why did you even vote vote him? | ||

Add this under 1) 3. Why did you vote with someone whom you had found suspicious only 30 minutes earlier, after such person (BH) only made one case that changed your mind? | ||

Answer: The gravitational force on the satellite acts toward the Earth inward along the radius of the satellite's orbit. The satellite's displacement at any moment is tangent to the circular orbit, in the direction of its velocity, perpendicular to the radius and perpendicular to the force of gravity. Therefore, the work done by gravity is zero. Hence, no work needs to be done against the force of gravity. Diff: 2 Page Ref: Sec. 7-1 2) List the three useful ways in physics to multiply vectors. Answer: 1. Multiplication of a vector by a scalar 2. Multiplication of one vector by a second vector to produce a scalar 3. Multiplication of one vector by a second vector to produce another vector Diff: 1 Page Ref: Sec. 7-2 3) State the work-energy principle. Answer: The net work done on an object is equal to the change in the object's kinetic energy. Diff: 1 Page Ref: Sec. 7-4 4) If the net work done on a certain object is zero, make a statement concerning its speed? Answer: If the net work done on an object is zero, it follows that its change in kinetic energy is also zero. Therefore, its speed remains constant. Diff: 1 Page Ref: Sec. 7-4 5) A force can be exerted on an object and yet do no work. Answer: TRUE Diff: 1 Page Ref: Sec. 7-1 6) If a force is directed perpendicular to the displacement, no work is done by that force. Answer: TRUE Diff: 1 Page Ref: Sec. 7-1 7) The scalar product is commutative. Answer: TRUE Diff: 1 Page Ref: Sec. 7-2 8) The scalar product is not distributive. Answer: FALSE Diff: 1 Page Ref: Sec. 7-2 9) The work done by a variable force in moving an object between two points is equal to the area under the force versus displacement curve between those two points. Answer: TRUE Diff: 1 Page Ref: Sec. 7-3 10) If the net work W is done on an object is positive, the object's kinetic energy increases by an amount W. Answer: TRUE Diff: 1 Page Ref: Sec. 7-4 11) If the net work W is done on an object is negative, the object's kinetic energy increases by an amount W. Answer: FALSE Diff: 1 Page Ref: Sec. 7-4 12) A net force exerted on an object opposite to the object's direction of motion decreases it speed and its kinetic energy.

A) Yes, since a force acts and the object moves, and work is force times distance. B) Yes, since it takes energy to turn an object. C) No, because the object has constant speed. D) No, because the object's displacement is zero. E) No, because the force and the displacement of the object are perpendicular.

Without at all addressing the points from Marv and from himself about DP's meta? And without addressing the other game in progress issue - which isn't an "unverifiable irl excuse," we can go look at the thread - and yet he comes up with a vote? guys what we have out of BH is not just a scummy and needless claim - we have a scummy and needless claim from a player who isn't playing up to his usual town standard in several ways - bad cases - trolling/fluff while taking the easy opportunity to gain points by attacking other people for fluff and most importantly - the huge mismatch in thread presence, thread control, and town organization between BH's last town game (whose line) and this game And then we have BH psychology: he just saw me do well - not win, except for self-declaring victory, but do much better than I should have given how the game started out - he saw me do well by fakeclaiming blue and then really pushing that fakeclaim hard. He also just had what I assume must be a trollgasm from evoking ridiculous reactions from Keirathi in that same game. Now he's claimed blue for no good reason, and it's a blue role that he can "verify" easily by withholding KP, or that he can make unverifiable by claiming to be roleblocked. There's no way a town BH decides "there are 3 or 4 votes on me, like 30 hours before the lynch - time to claim!" I just don't believe that thought process is real. ##vote: blazinghand ARE YOU FUCKING KIDDING??? THERE ARE NO COUNTERCLAIMS FROM A JK/RB, AND YOU WANT TO LYNCH A JK CLAIM DAY 1??? | ||

Iamp and marv What do you feel about the DP wagon going on? Honestly, I feel that his play is a null tell at this point. I'd be willing to give him a second day to shape up and show some usefulness. Meanwhile, Hopeless has acted like he is contributing and really hasn't done anything | ||
