@evan Its functionally not possible because you cant control the other server... its a mesh network afterall and the whole point is no one has the power to silence another.
Even if you block someone they can still leave replies to your posts (assuming you dont have authorized fetch, but then your posts arent public)
@freemo @evan
Not only that, but replies are posts, part of another person's timeline.
If someone is posting non-sequitors though, you should use the report button, see if server mods will do something about it. I know there have actually been server blocks for that, simply because it's a way for people from the Neo-Nazi servers to be disruptive.
Ahh ok.. it is good to hear a user doign that on a non-nazi server didnt cost the whole server to get blocked... that is much better.
That said any instance who would block a user from an entire instance simply for making polite comments that happened to engage a related but somewhat tangential topic.. that sounds like it would be a VERY toxic instance and not the kind of behavior anyone should be ok with, or encourage by reporting.
