From time to time I get emails from PayPal stating that someone sent me a small amount of money (always an odd number, between 5 and 21 Euro), and that I should register to claim this amount.
It is obviously a scam, because
- I don’t know the senders
- It’s to an email address I no longer use and that gets spammed frequently
- It’s from a PayPal affiliate in the country of the email domain (I no longer live there)
What is the game here? Is it to confirm my email address is real? Will they claim the money back? Or would I become a money laundering mule when they ask me to send the money back to a different account? I just can’t come up with anything that sounds remotely profitable to me.
Now, if this was a bank to bank ACH transfer, the recipient could just refuse the credit. There's an error code for this situation: R10: “Customer Advises Originator is Not Known to Receiver and/or Originator is Not Authorized by Receiver to Debit Receiver’s Account”.[1] You can contact your bank and refuse an incoming ACH transaction, which will generate this.
This is different from sending money back. It says to the banking system that the transaction was rejected and did not complete. So you're not sending the unknown originator your money. You're refusing to take their money. This eliminates the possibility of a reversal from their end costing you money. It also marks the transaction as an error in the banks at both ends. This is useful, because many errors on an account are an alarm condition and will get the attention of some fraud department.
If you have to reverse a transaction, do it fast. There are time limits for the simple paths.
(A friend of mine runs a bank branch of a major bank. Much of her day is spent straightening out error situations like this.)
