I a big fan of venmo, but it's crazy that they don't make it clear that your venmo balance can we reversed. There should be a "pending balance."

Also they should make it more clear about which types of payments are acceptable (though this is more of a complaint about TOS in general).

That's a problem with PayPal in general. I got scammed once because someone paid for something of mine with a stolen account, and the money was removed from my account almost two months after the transaction. I was rather alarmed, because it was long past the date after which I could deposit the money into my bank account, so I assumed by then that it was "safe".
