A lot of the work they do is aimed at thwarting the business models of cyber criminals, scam sites, etc.
Their reviews are probably from the people who had a good thing going using bots to scrape PII or take advantage of free trials/free tier SaaS products but were suddenly put out of business by cloudflares captcha tools.
During one of the mass exodus events from Reddit to Lemmy, a lot of people started using these tools they would install to automatically scrub and obfuscate their Reddit comments and posts history. Often these tools would replace posts with random letters and even nonsense links because there was suspicion that outright deleted posts could be detected and then programmatically restored if Reddit really wanted to get that user content back.
I suspect these tools probably exist for Lemmy as well and you are seeing users with long comment histories use them because those also happen to be the users who have a lot of previous content to cover up/obfuscate to maintain/ensure their own privacy.
