Names blurred to protect the innocent / crazy. Not trying to call anyone out, just thought the response was hilarious and highly disproportionate. Like, they distinguished that comment (green border/background).
For reference, the comment I presume that was downvoted that apparently triggered that response was to the tune of “BoTH SiDEz!!!” with some hyper generalizing / stereotyping on the side.
You can, at least partially.
If your instance is on 0.19.0 or above, you can block instances at the user level. You won’t see posts from any community there, but you will see posts from users there to communities on other instances, and you will still see comments from users on that instance.
It basically works as a “block all communities from this instance”.
