Regardless of what someone has or hasn't done, on a game we (or at least I) hope will be driven in future by mostly community run servers, am not fond of the idea of someones account getting banned from multiplayer as a whole for anything, really. From official servers and matchmaking though, do what you like i guess? Taleworlds playground to salt as they wish. But i don't think it's right to remove someones access from the game as a whole if they've paid for it and could be playing (in future, i know we ain't got server hosting yet) on an ecosystem outside yours.
