So,
Please don't blast me this is not a repost.
Of course you know Hasselhoff's great chineese scam.
Basically they fake to buy your WoW Account and send you the money at first, but then they will recall it as they have your account information.
Now what is a recall:
A recall is a disclaimer opened by a buyer on PayPal and unfortunately the buyer has 99.9% chance of winning for you (seller) have no proof to show to PayPal.
We can make this proof by ourselves.
So before he sends you the money ask him for his paypal e-mail address because you want to request the payment from him try and remember his PayPal e-mail address and sign it on a piece of paper.
IMPORTANT DO THIS BEFORE HE PAYS YOU!!!!
Go to a Fake Mailer as SOOM.CZ OR EVILPAGE.COM
Write an e-mail.
From

HIS PAYPAL E-MAIL)
To

YOUR PAYPAL EMAIL)
Content.
As you requested I send this e-mail to you as you have been
a great seller for me safe and legit.
You gave me your Digital product to me before I sent any kind of
payment.
I feel I really need to send this e-mail too you because I love the World of Warcraft Account.
Thanks you very much you are one
of the safest sellers on the web
Cheers

Have him send you the money and open disclaimer.
Use this e-mail you sent by yourself as a proof to PayPal.
ANOTHER E-MAIL YOU COULD MAKE:
FROM:His paypal
To your Paypal
Content HAHA SCAMMED YOU IDIOT JUST RECALLED THE MONEY FROM PAYPAL YOURE AN IDIOT HAHAHAHA I RULE!!!!!
LOVE YOUR ACCOUNT AND THE BEST PART IS I STOLE IT FROM YOU MUAHAHAHAHAHAHAHAHAHAHAHAH
(This one can be done after disclaimer is done)
Tested 2 times worked 1005 PayPal has to give you the money back.
