Unfortunaltly, If your account becomes banned. Your fucked legally speaking.
You pay for the right to have a login, the account belongs to SOE. So when you fuck up by cheating, SOE still let you keep the login you paid for, its just useless, since you cannot login to a banned account.
EULA makes it quite clear that you do not under any circumstance own the account, Hence why account selling is illegal. Your selling something that isnt yours.
Would be nice though, i had a 2year sub on an account and it got banned 2 months in, but to be fair, i was GKing Solteris before any guilds on the server had downed 2gods.
