You know, for all the flack Paypal has gotten, they've been pretty great in my experience.

We're using Paypal for our web game at http://clickerheroes.com/ and we have a pretty high number of disputes and chargebacks compared to average businesses (for obvious reasons, people want to get the paid stuff in the game for free).

We got a call from Paypal once when they noticed this, and they just wanted to know the reason for the high dispute/chargeback rate. I explained it to them, they understood, and that was the end of that.

Maybe the bad PR they used to get has made them change their ways. I doubt they'd ever do anything like what Stripe just did to the OP.
