That's why i prefer to work with actual people when shopping on secondhand marketplaces (i do not use ebay, but local alternative, not being in US). Support/protection from the marketplace itself can be used (and abused, both ways), but since it generally is automated (and i prefer to call it "automated", not "AI", because LLMs are not really "AI" and have nothing to do with "intelligence" - just another form of automation) it is much more pleasant and productive to use the marketplace to find people which can be trusted and communicate with them directly, often outside the platform. It works both ways too - sellers very much prefer a customer who is not going to screw them over, return faulty part, etc and often offer better prices this way (since platform fees are also avoided).
It is way, way too easy to scam with this old parts, there are multiple well known and unavoidable ways, so trust is all that exists to prevent that anyway...
IMO excessive use of automation will prove to be a downfall for many of online marketplaces, second hand and otherwise, at least those who will not recognize it in time. Cutting costs is well and good, but customers have certain reasons to use this platforms and once those reasons are gone people will find alternatives...
