<prompt> Human: Just received a Paypal notification that a random person sent me a few hundred dollars. Shortly after that, this person emailed me saying it was an accident and that I should refund them. I have no interest in keeping their money, but I want to make sure its not a scam first. It sounds a lot like the bad check scams that Ive read about where they ask you to deposit their check and then send them money back.  <response>: Here is a similar case from the perspective of the sender. Unless you have claimed the payment, it seems the sender can simply hit the cancel button. You can advise them to do so.
