A really unfortunately common occurrence.
Genuine sellers can help reduce the success of scammers by also accepting people paying securely if they prefer.
Unfortunately too often genuine sellers also insist on f+f payments only, normalising it for unsuspecting buyers..
I always say: please PayPal as friends, or pay the fee on top if you prefer to pay securely.
Secure payment fee is about 3%, + 1.5% for international currencies.
Meaning for €100 sale, the buyer would have to send €104.5 for me to get about 100€.
It’s not always exactly to the dollar especially with larger amounts but you can always send a few dollars as friends to correct any differences in the final transfer amount.
Better to be safe than sorry.
Watch out for unassuming/obscure scams too! Its not always big ticket items like Petri steering wheels, I once got done for a fucking €20 e9 interior light..
