I don't see what's the big deal with it. Yeah, it can get annoying if someone bumps a thread with something stupid like "Lol" or something equally as worthless. But what if they have something genuine to contribute to the thread? This is the only forum that I have been to that doesn't allow bumping of any kind. I feel that as long as a significant contribution has been made to a thread than there shouldn't be anything wrong with bumping it.
