I think swearing should be allowed, as long as it's not directed at someone. Something like "f***ing wall" would be allowed but not "you f***ing *****"... That's what the rule on swearing was in the game I played before Hyperspace. But their rules were way too strict anyway. For example they didn't allow you to call people "noobs", and you could be banned if an admin determined it was in a "derogatory" way.
