meta, mastodon, hackers.town
the situation with hackers.town is exactly the sort of thing a nomadic identity (as seen in hubzilla/zap/zot) is built for – users need to get away from an admin but in doing so, lose their posts and their connections. with nomadic id, all of a user’s posts can be syndicated on a server they’ve chosen to host their clone. if the time comes to switch, they do so and none of their connections would ever notice a change.
another thing: in masto, every communication, including DMs, is plainly visible to your admin. a lot of people have just been exposed to a fed. in hubzilla, and zap – in the underlying zot protocol itself – communications are strongly encrypted (presently aes-256, changeable in the future as needed) so that neither admins nor anyone intercepting communications can see any of them without breaking the encryption itself. your data is yours and is as safe as it can be. a fed running a server here would be ineffective and users not at their mercy.
