I can answer this one. Most jannies and mods on 4chan are leftist infiltrators from Reddit, they're the same gang of compromised corrupt pedos who worked for convicted sex trafficker Ghislaine Maxwell when she was the head moderator on Reddit, which was from about 2015 up until she was arrested last June. The ape who is in charge of moderation on 4chan only recently started the process of evicting the unwanted political infiltrators, there was a mass doxxing on /pol/ about 6 weeks ago, you can read about some of the fallout from that at
