I've seen skyscrapers with fewer flaws than the report this is based on. But seriously, the data is scraped. In my experience, these networks are pretty finicky about which comments they'll actually show you (even if they're not deleted). A lot of spam and hate speech is automagically nuked at point of post, or soon after. 8-10 minute scrape cadences are going to miss a large portion of good deletes, strongly concentrating bad deletes. There is no account for who deleted the comment; it's considered infeasible, but it's also said to be essential... Users deleting their own comments is censorship. It's no secret that many communities uphold a comment threshold far above the legal speech level. You should expect to play by house rules. That's not censorship. These seem like serious people, making a professional report, and they've put in a serious amount of work to code the comments they've seen, but every proportional argument is fatally flawed. Their source data is too flawed.
