If your interested in scamming people for "real" money or your selling an account and don't wanna get your money recalled here are some things to help.
First this is how u can make it so they cannot recall your money if your selling. Assuming you have all info let them log on etc and once they send the money, tell them to open up a dispute for the transaction and make up some bs then escalate to a claim, once done tell them to cancel the claim and tell paypal it was resolved. After they have done this the money is yours for good, they can no longer make a dispute or claim for that money again.
Second if your scamming someone's real money which is ****ed up but still people do it and how you can do this is make a paypal all fake info n stuff, and once u get the money transfer it to a different or your real paypal and then delete the paypal you got the money on before they open up dispute.
Hope some of this helps, and it's not a re-post if it is someone let me know and i got some other tricks to share.
