ok when i try to log on to batle.net on either us west or us east it says "unable to connect to battle.net" but i can log on to asia and the other 1. how can i tell if i am temporarily banned or permanently or what? it might have something to do with me trying a whole bunch of cd keys that i had earlier but none of them worked so i guess it could be the downloading using so many keys

Q u o t e:
2 weeks for use of invalid product keys.

Does that mean that they ban your account in this case? Or can they ban something else, they can't ban the IP, how does Battle.net identify one's PC?

Besides it's not possible to actually "use" invalid product keys, or is it?
