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].
That’s a celebrity. Nobody cares if you’re an average person and not too loud. Although the list of celebrities on the Wikipedia list of banned people from China seems to be people who did/said stuff while in China, often to an audience.
