Well, the PayPal is still the most common way to pay for many customers. I have such situation the second time within 10+ years on Boonex.
Someone would buy modules, get refunded and then post them somewhere on public forums in order to get more senseless "likes" on their profile from other "thankful" members for the "free nulled module".

Not talking about the particular case, but had such experience.

Weeks of hard sleepless-night work, testing and debugging are wasted for nothing. It's sad.
