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].
