Anatomy of a scam: Someone who just joined and has a listing with zero feedback. Yes, you are protected if you use CC/PayPal but bear in mind it may take a while before your CC/Paypal account is credited the amount lost on a bogus listing.
I buy from Ebay all the time, never got scammed buying new/used. I not only look at reviews but when they joined. I buy in confidence from longtime Ebay members (8 + years) and read the full listings to make sure they accept returns on big ticket items. The best way to prevent getting scammed is to buy only from "Top Rated Plus" members. You are guaranteed returns within 30 days from Ebay. Yes, items are more expensive but when paying $700 like in that bogus listing you'd be a fool not to. I purchased a Playstation 5 from a Top Rated Plus member March 2021 despite there being lots of scams for one. I paid over $200 more than other non-T.P.R. listings but I actually recieved a new Playstation 5 console, not a box of bricks.
There's always a risk with non-T.P.R. sellers but depending on the item/price I'll take the risk. LED Flashlight, used Bluetooth speaker or anything under $200 I'll take the risk providing the seller is longtime member and accepts returns. I've purchased a few used Laptops this way as well. I also like sellers that respond to questions within 24 hours using Ebay's messaging system. Those that ignore my queries don't get my money.
I completely avoid sellers who just joined - those are mostly likely fencing stolen property. That original listing for a $700 vintage video card? You gotta be kidding me. Even if that's the market value they better accept returns/refunds at that price level.
P.S., I don't do auctions, don't have the time or patience, with me it's "Buy it Now" or nothing.
