It seems to me like you (the ownership of Ferrarichat.com) are trying to work both sides of the fence. Your removal of privelages from users that don't pay may bring down the total number of users, but I say that this is bad business for you. If you like making money from the advertisers that support your site, you should encourage as many people to use the ferrarichat.com message boards as possible. Discouraging your user base from participation deprives your advertisers from reaching as many people as possible. If you'd like to keep your advertisers happy, you should guarantee them as much exposure as possible.
