I hear it all the time, but have not heard from anyone that has actually got a charge-back using personal gift (or any) option. It's always a friend of someone they knew or heard about.
The term "gift" used in the financial world has always meant non-reversible, does PayPal have access above the laws?
Anyway, let me know.
If I break into your house, steal a TV, and give it as a 'gift', this is reversible.
The scammer just complains that TEH BITCOINERS HACKED TEH ACCOUNT and the charge will be reversed.
