"Five people moderate the 92 largest subreddits." If that's true, why? How could an individual possibly have enough time and attention to moderate more than one subreddit with millions of users?
Both are great at posting and reposting (on and off Reddit, or between FB, Reddit, Twitter, etc), along with controlling botfarms.
edit: Seriously, why the downvotes? We had a NiFi post a week ago. And those of us who do OSINT and investigative work also use deanonymizing techniques. We automate our defenses as well using similar.
