It's unfair to issue a warning to one user, but give another user sanctuary by moving his comment into the Pigsty. This is obvious, isn't it?
Furthermore, we're told the TOS applies in the Pigsty just as it does on the rest of the site, so why should any post be more tolerated there than here? (That the TOS precludes all of the listed behaviors for which the Pigsty is intended is a contradiction that somehow goes uncommented upon, which is perhaps polite, since this contradiction gives away that the people making up the rules here aren't very bright.)
You've just issued a warning to me because I told Cornelius Blaze (poor tattletale!) that he must have been called a "lickspittle" once or twice before in his life (he was celebrating Jukebox Jury's ban and dismissing Kewpie's critics--these are almost the only kinds of posts that he makes). He was furthermore taunting a member who could no longer reply.
Did you issue a warning to him, as well, for his baiting of Jukebox Jury? Of course not.
Consistency: the mods here should give it a try, at some point. You've got nothing better to do, since there aren't enough posts on this forum to even justify having multiple moderators.
