@t_h_wyman Ultimately, what you as the seller are doing is a risk assessment. And while we may all assign different weight to different details (@keokusan played a good devil’s advocate), your point about the accumulation of evidence is real. What you are not doing is deciding if the person is a bad person or a scammer exactly, but really estimating the risk or probability that this goes bad and isn’t a likely net positive outcome for you. This is a very wise thing to do, and at the end of it you have to decide for your business model what kind of clients you want to service. And if you aren’t comfortable we are totally supportive of the seller responding with the “Decline Inquiry” button from the messages page.
Here’s an additional thought to my earlier point, re: forcing them to fill in their profile, and my concern about giving “sellers getting a false sense of security” because we don’t know if the information is correct. One way to look at it is, if we don’t require the name, you know who’s suspicious. A red flag is helpful to you. If we require everyone to fill in the boxes, then none will have this red flag. But does that make them any less risky?
Here’s a practical idea along the lines of what @stewart_reptiles said. Why don’t you reply to these people with a short statement asking them to fill out their buyer profile before proceeding? It will no doubt upset some but who cares, it’s a legitimate ask. The ones who get upset don’t understand that the seller faces risks too.
Btw @jdconstriction is going to do a related post about how to minimize the chances of a chargeback, soon.
