we have plenty of issues

I would venture to say that despite those issues, thanks to y'all's moderation this space is non-toxic on the whole. It may be that size is a de-facto limit on maintaining a space like Beehaw, or it may be that we (as in, internet users) just haven't figured out the best format/ structure for scaling up safely.

I think a microblogging platform that allows moderated, invite-only sub-groups (and which doesn't show you any posts by users or groups you don't subscribe to) could be a good step towards that. Sort of a combination of BlueSky feed + Beehaw communities/ FB groups. That could give you a Beehaw-like moderation experience in a microblog platform.

I think most microblogging platforms' failure in this area likely stems from them being ad and engagement-driven, and their corporate "need" for users to be more and more active across "interest domains", clashing with their users' need to stay isolated from users who are toxic to them.
