As others have mentioned the stars have been largely useless in the last little while so to be honest I’m not sure this has any impact. Even sites that try and give a rating based on fake reviews are not helpful because so many reviews are faked. The only helpful part is to try and read negative reviews.
I imagine this star fiasco is something that’s easy for browser plugins to reverse.
I would love to see AI and Machine Learning used to filter out fake reviews. This would actually be useful.
