Serious question: if it isn't true, and Roman was just lying or (to quote Greer) "done goofed", couldn't it still open the door for them to look into Reddit? His comment saying he works at Reddit comes across like a shitty joke so I don't necessarily believe it (yet), but that wouldn't matter to someone like Klein, who is completely invested (literally) in making these people suffer.
He might be lying about working at Reddit, but that doesn't necessarily mean there isn't some sort of favorable relationship between the people who moderate that subreddit, and Reddit itself. It seems to "conveniently" survive nuking even when other subreddits get removed for doing the exact same thing as H3 snark (like that Adam McIntyre subreddit, that got ICE on him and was quickly removed after).
"This guy doesn't work for Reddit, he's just a retard who has connections with Reddit that allows him to break the site rules with impunity" isn't that much better than "This guy literally works for Reddit and helped people break the law to financially harm someone they don't like" and while one is definitely worse, even joking about it sounds like a stupid idea when your opposition is in his pursuit of Jewish jihad (or Jewhad, if you will).
