okay, after reading
this old StLantny post I'm convinced guids is the same guy, as Stlantny stopped posting on 10/16/05 and guids registered on 10/24/05. Not that this is any significant relevation, as I'm not sure there was an overwhelmingly good reason to ban him in the first place. I'm just trying to insert some drama here.
ps. found the reason he was banned
here.
