As a buyer PayPal saved me after being scammed. It was a breeze to claim my money back, once I filed a police report.
Stripe and other normal card processors make it impossible. And before someone says to "charge back" with my bank, my card is from a country where that is almost impossible. In fact I think maybe only in the US that's actually practical, because in Germany I don't remember "charge backs" being a thing when i lived there.
Ive had the opposite experience with paypal being completely obnoxious and refusing to halt a fraudulent transaction (ultimately my bank made them).
