this is one of those things that's hard to enforce because the only form of rule enforcement is mods, and they aren't a good way to handle this kind of stuff.
what are they gonna do, count it as encouraging rule breakage? make its own rule? and who are they going to violate, the person who suggests it, or everyone that participates in it? or you could get lucid to patch it out entirely, but then people can forcelock games and last forever.
