Why do people keep trumpeting "but they didn't make any MONEY!"? The last time I checked, crimes don't require the criminal to make a profit to be punished.
While I personally have no want for a Vanilla server, I might have eventually got behind the idea as long as it didn't interfere with the development of the main game. Now, there's no way I'll EVER support the cause of a bunch of rule breakers. NEVER EVER
Unfortunately, this hurts those other folks who did nothing wrong and I feel bad for them. As for the rule breakers, I hope Blizzard dedicates a whole branch of their legal team to hunting you people down and stomping out every illegal server in existence. (even if it's just some dude and 3 people in some basement) Funny, I didn't even feel this way until a whole bunch of people came on here acting all entitled, flaunting the fact they there were breaking the rules and how little they cared that they were doing so.
PS, some advice to you vanilla seekers: Telling Blizzard how much you think their current game that they lovingly make sucks is not earning you any brownie points with them.
