I would enjoy a "block user" feature, to help this. I personally want to live in an online bubble of interesting thoughts. This seems close (or better, since people I enjoy can contradict my own flags) [1].
Haha, I feel the same way. I want to block and be blocked so I made this: https://overmod.org/
It's pretty easy to rewrite if you want. Just point Claude Code at the repo and go. But I think there's a little bit of network effects in that I want to subscribe to some trusted people's blocks too. But overall it's quite helpful. See how much fewer I get:
I'm torn on this. On one hand I do agree with your goal about wanting to live in a bubble of interesting thoughts. But on the other... I know I have my biases, and I'm sure I might end up blocking people who actually are insightful and interesting but either a) had an off day and shitposted, or b) says insightful things in ways that make me angry and get past my sense of reasonableness.
Good news, it doesn't block! It just puts a red mark next to their name, so you can put less effort into that comment, if you choose.
And, it's social. If someone you've marked green is also using this, and they marks someone green that you have marked red, then you'll see a contested red-green next to them, which is a good "you should probably reconsider" indicator.
