the whole star system is pointless and stupid because it does not explicitly indicates if what is being rated is the content or the distribution itself.
Some people use the stars to rate the content, how well it fits their expectations, or how they rate the production value (framing, lighting, image quality etc), some people use it to indicate that the content is faithful to what is advertised in the torrent page.
Some people will download a torrent, not like it, and still give 5 stars because it has good previews, good description, thumbnails included, etc.
There will be torrents where the uploader has clearly put a lot of effort, and it will be rated poorly because someone didn't like the actor, or because it lacked cum scenes, or they look too bored, etc...
Long story short, it was a lazy implementation that to this day nobody really cared enough to bother fixing its problems and making it useful.
tl;dr: don't waste your time looking at ratings.
