This is a good idea. Just have the revenue go into escrow immediately after the first claim though. That could reduce the motivation for fraudulent claimants since the payout is delayed. Also, to minimize overall cost, a creator can pay one fee to handle up to N open claims against them.

Overall, I’m not sure all of this addresses the asymmetric impact since it could disrupt the primary income stream of a creator, but it’s definitely a step in the right direction.
