Someone posted a spam thread in a wiki I go on and we can't figure out how to remove it. I'm not an admin or anything, just an ordinary user, but there is an admin who can't find a way to remove it either. When you try to edit the page, it redirects to a message wall. The thread is Thread:58758 and it redirects to Message_Wall:58758 so there is some connection there. Does anyone know how this was done or how to remove it?
