I've been thinking how it would be the perfect internet anon community for the last few days. So far I've come to two conclusions:

-It has to be slow. Quality of posts often comes inversely proportionated to how fast the posting is. Anyone who has lurked streaming chats knows this. Not only you can make longer, more thoughful posts, but also you can stay on topic for longer. I remember when someone linked 8chan's /cyber/ on /g/ and I was amazed on how long the posts were, that was how I imagined the old internet was. It also makes for a smaller, tighter community,

-No media, only text. I'm still a bit skeptical about this since images can add a lot of value, but mostly it's just noise. No images would mean no porn or avatarfagging who would keep sexual deviant groomers away. It would also discourage dopamine fried kids to post.

Now the real challenge is how to build the community, so far I think the best method is to start with a very niche topic to discuss (like some obscure anime) and build upon it. Another challenge is gatekeeping, it's clear you need to keep retards away but if you gatekeep too much you risk becoming a circlejerk like your typical small Discord server.
