There must be at least some minimal way scam listings are handled. I stumbled across an RTX 4090 going for $600 the other day (actual selling price is $1-2k), seller claiming to have 10+ of them with 90+ watchers/in cart, but no reputation. Account was gone the next morning.
Curiously on Mercari, which seems to be more pro-seller, I've seen some GPU listings with "this is a scam" type comments attached to them. Very different way of handling the transactions over there it seems.
Seller reputation is the only reason I still use eBay (when no other options are available). Even when I am desperate, a seller with fewer than 10-100 relevant positive reviews (depending on how expensive the item is) is a deal breaker.
