You have to understand that if you are banned on Bitcointalk, there is a solid reason for that.
Opening a thread such as this one can not help the matter. If I were you and I were convinced that all this was a terrible mistake, I would go and write one single private message to theymos, excusing myself and explaining the matter. Then I would wait and be very grateful if I got a reply back.
It's fine to have several accounts here, and I endorse that too, but rules are rules, and ban decisions are ban decisions. They don't happen by accident.
