I saw some of this while browsing earlier last week and making orders.

specifically, I remember at least one store that had wild prices on something I was looking at, so I checked the feedback and saw a store with zero activity for over a year, then a few recent, suspicious bits of feedback. iirc, it was like zero orders/feedback for over a year, then a bunch of feedback from orders that were placed a day or two previously. impossible.
