The only person I've ever experienced a problem with on gfy is theking. No, not personally..... smart ass
I mean, consistantly, I will reply to him and my post will appear above his. Someone else will reply to him, and their post will appear above his.
I've seen theking reply to a thread, and that thread sits at the very top of the board for a good 10-15 mins while people reply to other threads and they get listed second.
It's like any time he posts, the date gets set into the future by a few minutes or so, so anyone else's posts seem as though they come before his.
