How about this? I am sure Fencer can set it up. Have a 2 game tournament every six months. That way the top spot is up for grabs. Make it an 8 player tournament. It would be a required tournament and you could give each player like 2 or 3 days to make the move. To sweeten the pot so that these "phony players" will want to play put up a prize. This could be a 6 month membership, merchandise, or a cash reward.
