I recently received an email stating that a fellow from the United Kingdom sent me money via Paypal, a fairly modest sum of 16 pounds (about $21 American). The email address is slightly off (missing a period, but GMail considers it the same) and I don't recognize the name. I've sent the email to Paypal to ask if it's a scam, and I've tried contacting the person who sent the money, but I've received no response. Things look pretty valid in that all of the URLs are correct and, once I added that email as an email on my Paypal account (without the period), it shows a pending transfer.
The transfer is due to time out at the beginning of September and, unless I get confirmation from the sender that he intended to send me money, I'm probably going to cancel it so that he can get his money back, but it did occur to me that there has to be some risk to accepting money sent freely like this. What might I be missing?
