An anarchist-oriented Mastodon server has seen one of its admins raided by the FBI. The admin in question was working with an unencrypted backup of the Mastodon server, which was also seized.
Regardless, you are correct when it comes to privacy and security. It is important to note that none of the Fediverse is encrypted AFAIK(1) and server admins can see everything if they so desire. Most don't, but it's there.
(1) Almost forgot about Matrix, which is the most private of accessible messengers. It's worth checking out and you can interloop other messengers into it iirc. :)
Those pesky anarchists out here feeding the hungry and building dual power through community! If people can depend on each other for safety, security and human dignity how will the state continue to maintain its control!
Also, they use violence as a means of protest, only the police can use violence! No fair!
Haha, they're more likely to fight with each other than anyone else, I much prefer these kinds of extremes on the political spectrum. Many of my friends are anarchists and are probably some of the kindest hippies I have ever met.
