AFAIK, Theymos no longer answers mails sent to banappeals, altough it's the first time i hear an accusation that he would use the emaillist to spam somebody. This accusation seems strange to me, i don't think Theymos would do such a thing... Are you sure you didn't enter your email on some fishy sites?

As for your ban: can you give us a list of banned accounts, it makes things easyer when we try to find out why you were banned.

Last but not least: you are right, it is not forbidden to have multiple accounts... BUT: if even ONE of your accounts is banned, it's you (as a person) who is banned. If you continue using an account that wasn't banned, it's still called ban evasion (which is a bannable offence).
