The only thing I really have to add is on the topic of toxicity. Like you, I’m an instance admin and have a bird’s eye view of a lot of behavior patterns. I’ve recently started wondering how many people are here because they’re too toxic for regular social media rather than because they want to be here. I won’t guess an actual number, but I would say it’s not insignificant.

That's unfortunately a big issue with alternative social media platforms and without tools to combat them it goes bad really bad. I agree completely.
