Your account becomes dormant if you don't make any commission for certain amount of time. If you have balance in your account, they deduct $10 from it to keep your account active -- yeah the dirty bastards I know.
@#2 -- I think you are already part of the class if you have made any commission between the dates specified above and they will automatically apply credit to your account.
But yea -- the reality is that every affiliate network shaves. My friend who runs the affiliate network
Ads4Dough.com wrote network's side of opinion
