I see many ppl on localbitcoins uses it.
It's safe as long as the person who sends it is trustworthy, but most who appear trustworthy end up scamming eventually. All you have to do is complain to PayPal that you didnt issue the payment and you get your money back. As easy as that.
What to say to paypal, someone hacked my account or what?
Are you going to try scam somebody or something?
Whatever the case is nobody should be stupid enough to get PayPal scammed, and if they are - their problem.
