I believe the policy was that sites like sharkscope and OPR could not display certain information (like profit) unless a player opted-in by sending $.03 to them. You could also opt-out completely by sending another amt. If you do nothing they can just display limited info, like what tourneys you played and amount won.
It looks like sharkscope may be fighting this, since I noticed yesterday that they are now listed as prohibited software (or at least "pending").
