Most likely scenario. You really should try to avoid that situation for 500$. Or taking the risk hoping they'll drop the collection for that amount.
Or you can try with less ethical (and illegal) methods like throwaway accounts but it's tricky to do because you'll need a physical address to get the card and a lot of fake documents to verify the account/address.
But I'm really wondering if what I said would be a problem. I guess the person who got scammed (and lost his money due to his account was hacked or something) has to go after the scammer, not the one who received money from the scammer and just paid him btc, or am I wrong?
Its still going to be hard to get away from it, why not simply accept the payment through another method?
Something that is not reversible.
