I had been using Stripe for a short time a couple of years back. I looked into collecting sponsorships and donations for OSS development via BuyMeACoffee (I strongly advise against them). As expected, just a couple of bucks accumulated. Then a user sent an unsolicited $15 donation, along with an accompanying comment, asking for macOS user support, for help solving a user issue entirely unrelated to my project. I declined, explained the situation and offered to refund the donation. I never received a reply, but immediately after, I received a chargeback notification. Stripe took the $15 from my account as well as a $15 chargeback fee. The user claimed fraud. An appeal went unanswered, despite me providing all required proof. In the end, this little experiment cost me money. It also opens up a disturbing avenue of hurting someone financially, given enough credit cards and chargebacks.
