I agree that we don’t need to verify the number of points. Only that the individual has an account and that they are who they say they are. I think going through this process would be enough to deter scammers.
On the issue if a verified person scams someone, I would have a copy of the person’s Driver’s license that would include their address, which could be provided to the renter for legal recourse. I’ll have to come up with an authorization/disclosure/disclaimer form for the Seller to complete.
