you upset no one. this is not a personal issue. there are many reasons why private servers are bad besides the illegality of it, but i'll let that be a topic for another thread.

blizzard cannot shut down private servers as they are, how should i say... not the police? if i used your reasoning, then Louie Voutton would need to shut down Louie Boutton makers around the world. follow? this is not the case. companies are companies. laws are laws. law enforment is law enforcement.

edit2: multi-boxing will only be illegal if the game disallowed it. what you're comparing is a matter of "what seems" to you, or, your opinion. this has little to do with reality.
