I remember during the GPU shortage I managed to get a new graphics card from waiting outside a best buy for it to open. So I tried to sell my old one on eBay. Gave good pictures and followed all the rules as far as I could tell but because I had never sold anything on their platform before I was instantly banned with no way to appeal. I get they were probably having to deal with lots of scammers but if I could appeal or talk to support I could literally prove I had the GPU I was selling but as far as I could tell there was no option for that. So now I can't sell anything on eBay unless I get someone else to sell it for me.
