It's absurd on several levels. Someone at bliz is tired of fighting gold farmers so here comes a relatively easy policy to implement. Exceed 10 simultaneous logins and poof, ip ban. Great!

Wait, what? So now the burden is on us players? We have to call them up and let them know that there might be more than six accounts logging on at our lan party. These are BNet accounts not just wow so if 4 guys are playing SC2 and two others are playing WoW then some other guy fires up Diablo and poof were all down. And we're going to have to do this every time we want to have a lan party, just in case?

We have about 2-3 large lan parties a month. 10-50 people depending on the location. Guess now it's bring your own box, oh and make sure you call blizzard. You need to let them know that we might be playing their games. Bull S**t.
