I don't think trying to centralize a community that relies on a decentralized platform is a very great idea. I get what you're going for but I think the little pocket communities add a layer of safety from bad actors.

I don't think it's a "dupe". The same community can have different rules or expectations or culture in different places, and eventually, people will settle down where they feel comfortable. For some, that's the most populated place, for others, the one that aligns best with their own interests and vibe.

Personally, I'd rather not get invested in the .ml place, considering who's running the instance.
