Ran into a bunch of pro russian posts and bots. Gave them so much hell they had to run to reddit admins so now I have a three day ban. Apparently saying “good luck with that 21% interest rate and linking to the song 'speed the collapse” is hate speech.
Some fediverse apps support it. Voyager is one of them.
In Voyager, go to Settings -> User Tags
and you can enable it there. Then go the the user profile of the person you want to label, select the 3 dots at the top right side of the screen, then “Edit Tag”
Cheers.
