Saying "this is a human social problem" to me implies we should have similar solutions to what we have in meatspace on SSB. In the real world, you don't hang out with assholes, you leave places where they are, and you set up private spaces where only trusted people come in. You don't have to listen to people you don't want to, and if a friend of yours shows they don't have good judgement about who their friends are, you don't trust them to invite people to your house or go to things they invite you to (but you're less likely to be friends with them after a while).
Personally, I only want to see posts from my friends on Scuttlebutt, and I wish there were a way to set it that way (I especially don't want to see someone's posts if they only connection we have is a pub). Lately I've been feeling aversion to spending time browsing SSB, because it seems like every time I do there's some asshole troll. I got full on sealioned by PM yesterday, and I really don't have time or energy for it.
At this point in my life, I have no interest being subjected to BS. Yet I can't just happily scroll by abuse or bigotry, because if I am seeing it I know others less privileged are too, who will see it go unchallenged and become more likely to leave SSB (making this less and less somewhere I want to hang out).
I don't give a shit if I end up a complete no-asshole filter bubble. Sounds great to me. There are plenty of ideas to share and work to collaborate on with non-assholes. And unless I have tools to create an actual trust network, no way am I going to tell people who trust me that it's a safe place to come into. So hell yeah let's make technical solutions, and quite draconian ones at that.
The difference between SSB and whatever moderation goes on in the legacy web is that there is no central authority who can silence or ban anyone, and no global policies. If people want to wade right into cesspools or cavort with strangers, more power to them. But the design philosophy of SSB should be to give total power to each person to craft their own subjective reality, connections, and experience. That is how we'll see the incredible emergence of myriad diverse communities that I think it's SSB's destiny to bring about.
