Can I ask the moderators of this instance to delete my posts without a trace so that they are not in the federation database?
Is there a way to chat safely on Lemmy? Alas, I like to communicate with different people from different countries, because I can’t help myself, by the way, how then can I pass the keys to my matrix room to others or how can others give their keys?
Tips for online communication in a world where super-AI is perfect at finding people by their patterns and linking it to a person in a database.
You can get your local instance admins to delete the messages from its DB, but you can’t do anything for the other thousand or so federated instances, they all have a copy of the messages.
Safely depends on the content of your messages. But generally, consider your messages public.
“A super AI that is perfect at finding people” - firstly, doesn’t exist, secondly, by definition cannot be defeated. Otherwise, use e2ee when possible, and talk in person.
