Today I discovered that my website's tip jar was being used to test stolen credit cards. There were hundreds of attempted $1 charges over the last week. Thankfully @Stripe rejected most of them and only a handful went through, but I'm still stuck with $37 in processing fees. 💸
Only thing I could think of was to switch to manual capture of the charges. So I won't actually charge ppl unless I actually look at the charge first. That'll stop me from paying the txn fee that isn't refunded when I refund a charge.
