Venmo and Cash Out SCAM.

If the seller not accept payments inside the app, only the third party app (Cash Out or Venmo App). Money transfers may be useful when you want to send funds to someone you know and trust — but they're never a good idea when you're dealing with a stranger. Scammers pressure people to use money transfers so they can get the money before their victims realize they’ve been cheated. Money transfers are virtually the same as sending cash — there are no protections for the sender. Typically, there is no way you can reverse the transaction or trace the money.
