here are 2 suggestions. if there have to be 4 ways to get points then leave the new account points but put a max of 5 or 10 new users at most and also all those accounts should remain active for a week to be counted. secondly points for wins should be restricted to tournaments only. since pawns and rooks are in defferent categories it wouldnt affect anyone in the competition even if the points for rooks would rise dramatically versus pawns who can only join 1 tour at a time.
