If someone promotes the initiation of violence, I'll block them whether that violence is directed at me or not. (Even if the target of their violence is a bad guy)
;dr
@Pat That too. It's just a bizarre idea that a threat (or even just an insult) needs to be aimed directly at you for the blocking to be justified.
I put my general blocking criteria on my profile.
It's pretty much what you just described in you toot. I also block child porn.
And maybe graphic gore that's not CW'ed.
Sometimes I'll block someone if they only post a lot of stuff in a foreign language that I'll never read that it just fills up my feed.
Also, I'll block someone if they are unresponsive. If I respond their toots and they never answer back, I'll mute them so I don't waste time again talking to a vacuous poster.
Other than that I try to resist blocking people.
@Pat I try to resist too ... but not nearly as hard as I used to. 😀
There's another aspect of this...
Some people are neuro-divergent and may have difficulty communicating or whatever, so I try to give the benefit of the doubt. But that depends on my mood at the time. 🙂
