Here is what has happened, and what will happen in the short future :
A) The code changed so radically (SC 3.0) that using existing hacks simply doesn't work. This is because the way hacks used to "update" was for the developer to look for a slight change after a patch, and update their hack. This doesn't work anymore.
B) This means that 3.0 threw a monkey wrench into the machine that is hacking, and this doesn't break hacking, it simply means that you've slowed down the process indefinitely; until someone writes a new hack for 3.0 After this happens, it's the exact same process as before.
C) This isn't easy to achieve, but is entirely possible and will happen most likely within a few weeks. This also gives a unique opportunity for someone to monopolize the hacking community (for sc2), as valiantchaos essentially did. So in other words, there is a very strong motivation factor to consider, which means new hack(s) will be out sooner than later.
TL;DR Hacking has been slowed to a halt, but will be back within a few weeks, just as strong as ever. This is not a solution to hacking, nor even a strategy, more or less an affect due to a new interface and radical changes to code. sc2 3.0
I wish a mod would change the title and even add a little information, as this thread has clearly convinced several people of something that is absolutely ridiculous.
