The buyer could simply file under "Unauthorized Charges" or "Didn't receive product" claim. I read cases that many sellers have lost their cases, including Twitch streamers.
I could produce evidences such as emails but I doubt PP's policy would deem them sufficient.
For digital products, it's not easy to avoid charge backs because there are no tracking numbers or physical products.
this depends on where u get your customers
example:
say u r selling digital key for pc games
IF you get most of your customers from PAID pc magazines in which the users need to pay to read the magazine, chances of fraud (charge-back) is low
IF you get most of your customers from FREE reviews, warez like bittorrent or piratebay, then... you should know what u r getting yourself into
this is the primary reason why certain magazines + publication charge tons of $ for ads, while others like FREE websites no one want to advertise.
