Paypal is truly the worst. I just had someone "accidentally" put $130 into my account and then email me saying I stole the money and to return it to them right away. Of course I just ignored this person. They even tried to contact me on facebook messenger! In the end paypal reversed the transaction without me having to do anything. I guarantee if I had sent that money back I would be out $130 right now.
Paypal also is still holding $150 I tried to use to buy a painting by a Cuban artist (in Miami). Because the transaction had the word "Cuban" in it they are basically going to hold my money until I get a letter from the treasury department...
