> Now I'm more confused as your answer mentions they are not supporting Mastadon servers that don't censor porn, hookers, and strippers - so 'not supporting' maybe that's what I should of been asking about, I guess that means they are not banning users, just making it so their user's services can not connect? Keybase has this concept of Identity Proofs. You put a special signature on a page in a specific way that Keybase has vetted. For example, I can put a signature on my HN about page (which I have), give Keybase my username and they can prove that the HN user is me which proves to other Keybase users that I am real (i.e., not a bot nor a fake profile created for trolling/nefarious purposes). On it's own, my HN proof isn't very strong but coupled with other services and I now have a complex profile of proofs that spreads the social vetting across multiple companies/organizations. Mastodon is a social messaging platform like twitter mixed with custom message boards of the 90s/00s. The key bit from the latter is that each "instance" is run by anyone on their own hardware with their own level of security determined by whomever administrates the server. Keybase (according to the comments linked above) decided that they would only be setting up this Identity Proofing with the most general instances and not with more specialized topic instances (particularly sex work or porn) because (these are my assumptions wrt their reasoning) there is a time cost to setting this stuff up but also to not align themselves with instances that may be taboo to some of their userbase (read: potential paying clients). To get to the point: Keybase does not have read access to your content (they use E2E encryption), but they do make certain decisions about how their tools integrate with the outside world. I don't know their politics but I would guess that since they are working towards finding clients to setup custom instances of their model (to start making money), they are just trying to avoid misaligning themselves.
