The guy probably uses VCCS and fake phone numbers etc to get uber. The drivers won't be paid, and he will not pay anything to uber.
Whoever that uses this service might get in trouble when uber finds out. It is illegal,so may also bring you I to jail.
This is a newbie providing a service, maybe it's a scam and he will never get you a uber drive and walk away with the money, so always use escrow
Well, it's probably not a "scam" since you can pay after the trip. Yes, it might be that the drivers won't get paid (which you should feel bad about), but it also might be that the OP is cracking Uber accounts and then ordering trips via unsuspecting Uber clients who have no affiliation with it.
Don't order this.
