edit: IF YOU DON'T READ THIS PART DON'T BOTHER REPLYING......
It seems that buki was already in GM and stayed in due to the system. As he can only be removed by inactivity and bonus pool accumulating, losing 130 games in a row doesn't demote the account from GM. I'm curious whether the lowered MMR will make it impossible to get back into GM next season, but either way the intentional losing is bannable.

He has defended himself saying he was just trolling by being a GM playing bronzies, which explains what happened, though still brings up concerns of abuse and some problems with the current system.

Original Post:

Today I looked at the NA Grandmaster's league list and noticed a player with a very unusually low win/loss ratio.

Two days ago this player who had a normal account playing lots of games suddenly starts losing...

[image loading]

A lot.

[image loading]

The players mBnBuki was losing to were in bronze and eventually the account's MMR was reset and no longer lost points for losing a game. The loss streak was 130 games total.

[image loading]

[image loading]

mBnBuki then went on a massive winning streak going 32-3 before being promoted to GM with the last loss...

Against a silver league player.

And here's a random picture from a local lan, featuring my friend ProfessorOak.

The one with the face. (Second from the left)

The picture is unrelated to the topic, also.

Everyone knows the GM system is broken in NA, has been all season.
With a season reset in a short while, where hopefully Blizz will fix it, it won't matter.

Although it is funny to see exactly how broken it is.
HOLY CHECK!

Has the new season started already? I thought the GM league was locked?

Anyways, it is known that GM has been bugged for some time already.

Well knowing if he did abuse the ladder I would not be surprised if they banned him. Actually knowing blizzard, I wouldn't be surprised if they didn't anyway.

Awesome,

I don't quite get how this works though, I thought GM selection just took players within a certain MMR range of the best ? If he has silver level MMR this shouldn't quite work ?

I'm having trouble understanding how there can be so many screw up with a system that's relatively straightforward to program.

I'm pretty sure the lock starts at December 13th

Wow thats sad, and weird, that it is so exploitable... I guess most people in GM really should be there so this isnt a massive problem, but still... wow.
Crazy people dont sit around and wonder if they are insane

MMR is completely independent from league, for all we know the other guy was doing the same.

I guess they should make sure anyone promoted to GM should be in Master first, but ladder is serious business.

The guy should be banned for throwing 130 games, not getting into GM league.

The division system is still bad and there's no reason a closed league (by number of spots) should even exist, especially if it flat out doesn't work and is exploitable like we see here.

GM should just be masters league and top200 by points should get the orange icons.

The problem with GM is that it's not actually invite only. There's a system, and when there's a system, it's going to be beaten by some derp.

Way to avoid this? Make GM actually an "invite only" league. Why not? Get the top pros, with some room to cycle new up and comers into it, and let em duke it out. But atm ladder has no worth so who cares :D

You can't ban him for throwing 130 games lol
Also I have no idea how he did this, it doesnt make sense that other farmers didn't get GM this way... :S

Getting promoted into GM should force you to play a BoX with a grandmaster to show your worth, not beat random ladder players until you have accumulated enough MMR to get inside it.

Imo, I think its fine. He found an exploit, report to blizzard and hope they fix it so it can't happen again.

Ye it looks to me he lost 130 games in a row on purpose just to get down to bronze. I don't think him getting into gm is the problem, he's probably good enough for gm if he got there it's the fact that he lost on purpose just to own bronzers. It ruins things for those people having to face him, both when he lost on purpose and when they later didn't stand a chance.

Also I have no idea how he did this, I've done this myself too, throwing myself in bronze, i've won literally 100 in a row but I was still in bronze...


Yes, you can. Blizzard said it's a bannable offense.
