Evidence No. 3783 that "social media" and "privacy" do not mix well together.
Let me repeat one more time:
- anything you write online should be considered public.
- There is no "consent-based" fediverse.
- There is no "GDPR protects me from that".
- There is no "security through obscurity".
- There is no "dark corner of the internet".
No matter your morals and ethical values, If you need to have any type of conversation that you think might get you in legal trouble, do not have this conversation in a public forum. Use #matrix if you have to, and even then you'd still need to worry large group chats which may have some undercover agent.
And if you are really concerned about "censorship", then ActivityPub is not for you. Go join forces with the bitcoiners and use #nostr.
