I am not aware of any.

It takes me about 20 hours to put together a complaint, and then adding court filing fees and service fees you are going to spend at least $5,000 to just to file suit at Day One, so you need to be assured of some return on that expense to make it worthwhile. Expect $35,000 in costs to "go to court" and hope that you win damages AND attorney's fees.
It would not surprise me that some will shave joins because they know that the small affiliates cannot afford to fight for what is rightfully theirs.
