8bit and FJ both behaved shilly, FJ even more than 8bit. I believe it is inevitable that the board admin will become infiltrated, the thing is that they walk on a very thin cord, so they can't go all out and start banning anons.
As for the 8ch shutdown, I was present when it happened. It was almost at the graveyard shift, the baker was a muhjew shill, and the board was infested by shills spamming inflammatory garbage (80% of all posts). Then all of a sudden the board went out, and all so conveniently, the cached page that was visible to anyone who attempted to reach 8chan, contained all the shill garbage with no anon response. This shit show was visible for many hours until CM finally took the entire domain.
imo the "circuit failure" was a deliberate sabotage, aimed at smearing the q movement while giving fuel to the "independent msm researchers" who study the "evil qanon conspiracy".
