Potential Scam?

[c4po]

Someone has "accidentally" sent me a payment of $500 out of nowhere and is asking me to refund it. I would be happy to do so but I'm afraid it might be a scam to get me to pay $500 of my own dollars. I haven't accepted the funds yet. Is there any way to just decline the funds instead of refunding it, and if not, is it safe to refund the $500?

If its not in your paypal balance and its asking you to accept it then don't do so.

If you accept it and refund you will be charged a fee and not get that fee back when you refund.

But if you don't accept it then it should time out at 30 days and go back to the sender.
