There are a lot of tanky posts coming from lemmy.ml. Their whole purpose seems to be to troll and spread their bullshit far and wide. They are nearly as bad as the alt-right. They argue in bad faith and celebrate authoritarian oppression. The beehaw mods might want to consider defederating.
My experiences with beehaw users have also been largely positive, but I don’t really use my alt that much, so I don’t have many encounters.
