Paypal already has a policy for dealing with users who reverse transactions out from under them. Unfortunately for the users, that policy is known as "scorched earth". We're talking account suspensions and referrals to collection agencies.

It would certainly be a lot less skeevy if it was done for a service-oriented reason (i.e. one way transactions) instead of the "because fuck you" reason that they appear to use currently.
