Seems like all of these profiles have been created for the sole purpose of downgrading Racket Boys. The reviews are the same in at least 4 episodes, that are rated tops as 2 and they are providing a description from netflix in the details instead of actually writing a review. Besides that, all three accounts have been created the same date that the reviews were written and they haven't been online since then (and they have all rated the series as 1 having watched zero episodes).  

This user kept posting about escort services in forums, and their profile page is full of spammy links:
