Thanks for the info. I was not aware that Bluesky had public, shareable block lists. That is indeed a great feature.

For anyone else like me who was not aware, I found this site with an index of a lot of public block lists: https://blueskydirectory.com/lists . I was not able to load some of them, but others did load successfully. Maybe some were deleted or are not public? I'm not sure.

I've never been heavily invested in microblogging, so my first-hand experience is limited and mostly academic. I have accounts on Mastodon and Bluesky, though. I would not have realized this feature was available in Bluesky if you hadn't mentioned it and I didn't find that index site in a web search. It doesn't seem easily discoverable within Bluesky's own UI.

Edit: I agree, of course, that there is a larger systemic problem at the society level. I recently read this excellent piece (very long but worth it!) that talks a bit about how that relates to social media: https://www.wrecka.ge/against-the-dark-forest/ . Here's a relevant excerpt:

If this truly is the case—if the only way to improve our public internet is to convert all humans one by one to a state of greater enlightenment—then a full retreat into the bushes is the only reasonable course.

But it isn’t the case. Because yes, the existence of dipshits is indeed unfixable, but building arrays of Dipshit Accelerators that allow a small number of bad actors to build destructive empires defended by Dipshit Armies is a choice. The refusal to genuinely remodel that machinery when its harms first appear is another choice. Mega-platform executives, themselves frequently dipshits, who make these choices, lie about them to governments and ordinary people, and refuse to materially alter them.
