2 days ago my friend's Battle.net account was suspended for 2 days because of letting his friend 2 states away play on this 2nd account on the same battle.net account.
If this is you I would suggest telling your friend to "stfu get jo own account bitch" <- Maybe in a nice way O.o
Just to let everyone know
P.S. Don't merge your accounts (like I did). About 2 weeks after I merged my account i was like "I R SEL ME 1ST ACC AND KEPE SECUND!....DOH!"...****ing battle.net.
Hope Blizzard doesn't make this mandatory anytime soon.
DON'T FALL TO THEIR GRASP!
