Technical mind. Always learning.
One of the things that make Twitter attractive for me is the fact that my feed contains tweets from people I don't follow (and I don't want to follow), but which very well match my interests.
It would be great if Nostr has that feature too.
If the credentials are type on a computer, I would say the most likely scenario is the computer is compromised, a virus.
Make a backup, format the system and start from scratch.
I would recommend Ubuntu instead of Windows. Blocking all ports for incoming connections is very easy on Ubuntu with the ufw command. Not so easy on Windows.
