Well, you can throw a tantrum, but is not gonna make the house rule go away. I suggest dealing with it.
OP still raises a valid point. It is daft that people who voluntarily turn off the profanity filter (didnt even know it was possible, but cool!) complain about being confronted with profanity. It is also daft that FD still has a very, very lenient stance on known cheaters. Suggesting to 'just deal with it' isn't very sensible in the context of a discussion forum that explicitly exists to discuss this game.
