• Literal Neo-Nazi site. Defederated by nearly all of Fedi because they are literal, card-carrying Nazis.
• Transphobia-even-if-it-means-misogyny site run by his wife. Defederated by most of fedi, for harassment campaigns. Defederated from my instance for harassing a cis woman who worked at a feminist charity for, as I recall, having pronouns in her bio, which is apparently too much like solidarity for them. (There were a couple of good people on that instance, last time I checked. Well, one good person. I think she messaged me later, saying she left.)
• His personal instance that basically nobody uses. (It's too obscure to be blocked by most of Fedi, but it's blocked by most of the instances he tries to interact with; he inevitably breaks their rules.)
• shitposter.club: A kinda-okay, but not moderated to my taste, instance. Blocked by some of fedi; probably on the list because they still federate with his personal instance.
• freespeechextremist.com: A barely moderated instance that… well, I trust its sysadmin – sorry, its BOFH. And it is friendly. But it's a "free speech zone", with all that entails; there are some total arseholes there, and the only thing keeping them from causing major damage is the relentless bullying they get from the other users until they leave.
The bottom two are legitimately part of the Fediverse – albeit the shady alleyways of the Fediverse – but we've almost universally shunned the top three. This developer used SEO hacks to get his fake near the top of the search results. (Please don't link it here; we don't need to give it more SEO juice.)
He does not represent the people who make the protocols; he does not represent the people who curate the communities; he does not represent the communities; and yet he claims to, all the while decrying how mean the community is being to him.
We just want to live our lives, and use the 'net to talk to each other. If anyone's making this political, it's him.
