Clever scammers don't leave neutrals and negatives.  They don't leave any trace of their habits.

I had one that glowing feedback, but they were a scammer, their spiel re not described was too well rehearsed.

After I looked at the "staged" photos they sent through of what was an immaculate garment I knew for sure they were.

I "lured" them into opening a paypal disute, and then I escalated it to a claim myself and did not cave to their demands -  they backed off and requested that paypal closed the case as all was sorted - lol, sorted, yeah right.

The vast majority of sellers don't put any follow up comments to their own, or in a buyers feedback, when they have refunded.

What appears to be, isn't always what is going on.
