As I understand it, PayPal acts as an escrow.
I'd be careful about making that assumption. Paypal is nothing like an escrow. They don't hold the funds until the buyer approves the product and OKs the release of the funds, which is how escrow works.
As a buyer, your best protection is to make your Paypal payment with a credit card. Then, you have the credit card dispute process to back you up.
I once made a Paypal payment by mistake to an unintended account. I did this simply by making one wrong keystroke. I contacted the other party and requested a refund. No refund. I opened a Paypal dispute process. No refund. Essentially, all Paypal did was contect the other party via email and request a refund, but they had no power to force a refund. After three months, Paypal said the other party never responded to their requests, and therefore the dispute was closed.
If you consider Paypal a safe method because of its buyer protection process, then I think you are flying without a net. This is why I always pay with a credit card when using Paypal. I know I can rely on my credit card company to help in the event of a problem.
IMO. FWIW.
