Goku, if this "legislation" was in place, then even moar congressmen will be turned away from their own country's community. It's like banning people from the forums for making a mistake. There's simply no point other than to alienate other members of the community if they get a little "hot-headed" like a good friend of yours. The forum mods can control their own jurisdiction, but I don't see why they would have to attempt to police outside the forums. They aren't a teacher you can tattle to.
I'm sure johno had the best intentions when he made the proposal, but let's be honest, it's just him trying to roleplay the commie looking out for everyone. It will be abused, and it will get annoying for a lot of people. If people are really upset by a few words someone says to them when they're playing erepublik, we all know the simple solution, don't we?
