Yeah, this on has been around for a while now. It works like this:
1 - Scammer contacts the seller and tellsthem they are happy to buy for the advertised price, sight unseen, and they work somewhere remote and can't be contacted;
2 - They ask you for your PayPal email address so they can "deposit" the money;
3 - They send you a fake PayPal payment notification which asks you to sign in to complete the transfer;
4 - Unaware person signs in using their username and password, sending it directly to the scammer;
5 - Scammer goes to town on persons PayPal account, unbeknown to the victim;
6 - Rinse and repeat.
Do not ever believe anyone who asks for your details to make a payment through PayPal. Ask for their PayPal email and send them an invoice - simple. Actually, that goes for any emails asking you to sign in to confirm your password or something similar - banks will never do that and the only time you should ever enter your password is when you see the little padlock up in the address bar to indicate it is a secure site.
