It's a real thing on my account page too, and I get emails about it. Just kinda weird, I'm not doing it.
Someone once told me the wrong account to send money to, so he called up PayPal quickly and actually got a live person.
Funny thing was, he decided to mail what I bought anyway to make up for the inconvenience, I didn't like what I saw, so I was left with both my money and the product, which I just mailed back without having to fight for a refund.
