I think one of the issues might be if you’re subscribed to an active community of a few hundred people the fear is that community would mutate if suddenly a few thousand new accounts joined it and you could lose what you’d made.

Having said that, would I like a world where a ‘gram influencer stumbles in to a hexbear or .ml community and posts some vapid “sponsored content”? Yes. Yes I would. Would I like to see an evangelical turn up at Blahaj (sp?)? Yes. Very much so. Not for the drama - but to discover the contrast to their own personal truth. But, like you say, the tool-o-meter is already throwing out readings as it is, so everything would probably descend into name calling and bad faith arguments.
