This isn’t just relevant to Lemmy because it’s culturally intertwined with Lemmy but also because there’s a search engine database now that acts as a registry for anyone promoting any of the mass shooters (Luigi, Robin, Tyler, etc.).
China currently bans anyone from entering who denies their narrative about Tiananmen Square. It’s the same deal here. There’s also a couple of already-controversial Lemmy users who are collaborating with the US government by judas-kissing everyone after having honeypotted them. One of them having been infamous for banning people who promoted “blind alignment with Luigi Mangione” [sic].
For better or worse, the government isn’t dumb and they’re aware not everyone in the fediverse is who they’re looking for. The fediverse is very feudal, and the government has occasionally popped in to subtly ask the disillusioned for pointers, since simple spying often leads to questions. So there’s active collaboration here.
Keep in mind this is a recent development in fairly old news. Trump was known in the beginning to vet immigrants for their social media presence. The freedom from lèse-majesté as it’s called has been broken.
I’ve reported you to the US government. Removal pending
So no, you can’t name them. Or really have anything but speculation
