Uh-huh, then you'll wait for some bonehead or sometimes yourself to bump the thread.
so what if it gets bumped, that doesnt mean anything bad will happen to the gamemodes that are good. It doesnt matter
edit:
for example theres the occasional joke topic in gallery, usually involving someone posting a topic along the lines of "greatest build ever!" and its a pic of a 1x1. It's not real content, but in the end its just a joke and the topic dies. In both cases there is nothing to worry about
