what can be done about it

Hi! So Im a member of a huge swedish forum for free speach https://www.flashback.org/ 1.3 million users since 1997, that is often under all sorts of attacks and have to deal with lots of trolls and also authorities and attacks, leaks etc. They have a few admins and lots of mods. The way they dealt with these issues is quite authoritarian and also arbitrary but it kinda works. They made a new rule called quality before quantity. It is only the admin that can enforce, and basicly it means that the admin has the power to remove a post or ban a user completely at his own volition. Obvioulsy people complained and it is rarely used. But admin there is sort of beyond reproach, and highly trusted, and in the end he says "well if you dont like it just leave this is a private forum". Keeps a lot of bs at bay. Just throwing this out there. Good luck with everything.
