It's sad to see, but you can tell when people try to inflate their profile stats by creating one-time accounts to "buy" their listings and leave positive 5 star reviews. It's even worse when they decide to try and do multiple reviews/comments on the same day. Makes it way too obvious that they are simply boosting their main account.
Example 1:
This user

Many listings have many reviews made on the same day. Kinda fishy.
Example 2:
https://xmrbazaar.com/listing/E2EW/
This listing has 12 upvotes, with very little description. All of their other listings have 0 upvotes.

Am I being to skeptical? Have you noticed this yourself? I'd prefer true, organic growth for profile reputation and not fabricated numbers. What do you guys think?
