Yes, and sell a soul also. It is OK IMHO If acc purchaser does something bad he will get trollhammer banhammer.
Purchaser might get exclusive dumbass title also. There is no real need to buy acc in this forum as post count gives nothing when noob level is left. He is different person and the schizophrenia of personality change will be noticed and trust will be lost.
Technically you do own exclusive ownership of your soul (property) and maintain a right to sale unless it's been bargained away to some other entity that retains a right to ownership. Could you lease ownership of your soul? Sell your soul as a service? That would make for an interesting discussion.
