There wereultiple cross-posts daily pointing to specific threads posted on hexbear to organize brigading.
Yeah, I do remember that. That's why I'm not signed up there. They weren't changing anyone's minds with their shitstirring and were doing it for their own enjoyment (which is damaging to all communities, even nonpolitical ones, if people avoid your platform due to trolling).
That said, it was a past problem, and posters on lemmy.world are still out there complaining about Hexbear like they're relevant. I'm speaking about the current situation.
I'm not advocating for them to re-federate with lemmy.world (I have no dog in the race, anyway, being a part of neither instance) but I do remember watching the Hexbear mods/admins shutting down the actual brigading of threads before lemmy.world de-federated. Not sure it was a solvable problem, anyway, Hexbear is rather antagonistic in ways I don't agree with.
Ah yea, everyone that has an opinion that isn't mine is dangerous and deserves to be silenced. I totally agree. I think lemmy.world should refederate, and then defederate a second time, just to make sure they get the message.
