Any processing fee should only go to a third party, otherwise you'll have a hard time avoiding bad incentives. Even for something like youtube, were you already have three parties, any arbitrator should be mostly independent from google, since they have a lot of control about what conflicts emerge in the first place (think content ID, punishments for false DMCAs, etc). But i really cannot understand why something like this doesn't already exist. Imagine how many false DMCA conflicts could be avoided if both parties had to place a $5 deposit to get a human ruling. And the $5 of the losing party should easily be enough to compensate the arbitrators work for most conflicts. Building such a mechanical turk like small claims online arbitration service seems easy and no matter how hard I try, I cannot come up with any reason youtube wouldn't want to use such a service. So why does it not exist already?
