I saw this seller a couple of years ago, doing the same thing. Essentially, she is selling "rebranded PLR" as "clickbank-ready" rubbish. The main problem is, PLR products are poor quality and the new owner will get hit with refund requests from clickbank.
At the time i first looked, the sites were like
http://internetmarketingturbokiller.com, for a product and website branded with internetmarketingkiller. I asked if the product was unique(says graphics are unique, doesnt mention the product actually is), I got a caustic response such as "are you kidding me, of cause its not unqiue, a unique product would cost low 4 figures". Any comments like this get deleted from her auctions. Which is weird, as when they are deleted they look like they didnt appear at all, whereas when other auctions have deleted comments, they show as deleted, so obviously very friendly with the flippa owners.
I never worked out her exact method, as even an account with top feedback, and big sales wouldnt achieve this result, I would assume she has a marketing list from a blog or something. If anyone knows the missing piece of the puzzle pm me.
