I like Anonup a lot. I feel like Gab is worth a go; I am unattached to any of these platforms. Social media needs to be like email, where nobody owns it, and you just need a protocol to be agreed upon. My domain can point to my "SX" record to subscribe and publish messages. We might choose to also use centralised hubs to speed exchange, but they all need to be a "nice to have"; I am willing to wait a bit for replies and feeds if that's the prices of no censorship.
