Surely the risks are no different from selling on ebay.
In fact, the risks are far greater, because the seller has
no proof of a legal transaction at all. The buyer didn't purchase through an Ebay auction, so there's no paper trail. So here's the pattern of what could likely happen:
1: Buyer sends money via PayPal for real, seller mails out the whatever, buyer is happy, and all is fine.
2: Buyer sends money via PayPal for real, seller mails out the whatever, buyer says it was never received (maybe it really was stolen at the door by a rental neighbor, maybe buyer is trying to get it for free), seller can't prove it to PayPal's satisfaction: PayPal will refund.
3: Buyer sends money via PayPal for real, seller mails out whatever, buyer says he didn't really send the money, it was some sort of fraud and he's a victim: PayPal will refund, and most likely lock the sellers PayPal account until they provide all sorts of documentation.
4: Buyers PayPal account really was hijacked, and they really didn't send money at all, seller was fooled: PayPal will refund, and most likely lock the sellers PayPal account until seller can provide all sorts of documentation.
I've been through some of these scenarios on the sellers side, and believe me, it's very stressful and dealing with PayPal can be like dealing with the Devil. Or like dealing with a Honey Badger, and we all know a Honey Badger
just don't care.
