Hi and welcome to the GOF!
I really don't remember any bannishment from the GOF because of an Avatar. What kind of Avatar was that anyway?
I'm positive that nobody would be banned for an Avatar without a previous request to change it unless that avatar was of highly offensive or criminal content.
As I said, welcome to the GOF, but please do not tell stories about some kind of harsh banishment policy which does not exist in the GOF. Looking at LBTlovers response it seems that the difficulties you had were not the admins' fault.
