How about this:
-stop caring about troonworld's niggers and focus on making your site more decentralized if you want to attract new users. you don't need to seek their approval.
-let users discuss whatever they want as long it's doom-related, community drama is NOT off-topic.
-let users have the freedom to shit-talk/criticize/discuss other people's work as long they don't promote irl harassment/doxxing.
-enable IDs to stop samefagging.
-people already mentioned it, but remove the censor filter.
If i'm being honest, I really doubt your site is going to survive. in a worst case scenario, 4chan will be back up soon and people will just return to posting there. what are you going to do about it? I think you missed the chance to create a new forum instead of yet another anonymous board. but that's just my opinion.
