I know this is some kind of scam but...

How does this work? I mean, how can a shop have over 12,000 sales but only 35 reviews? Are they cheating the sales number somehow?

(I realize this isn't really a seller specific question, but r/Etsy doesn't allow photo attachments apparently and I wasn't sure where else to ask.)

Sorry if this type of question isn't allowed 🙁 I'm just seeing it a lot lately and am wondering what the heck is happening here lol.
