For example, I downloaded Tor network and using it for illegal activities. Can my govt track me? Can US govt track me? I know it encrypts something but if I remember correct, FBI was able to find some Tor users before.
Note: illegal activities was for example. I’m not going to do anything illegal. I’m just planning to serve my instance with a onion address.
Don't do illegal activities.
What signal fiasco?
You should read the Tor foundation documentation before trusting your freedom to it.
You can be tracked on Tor, but the question is by who, and when. If you login to gmail over tor then google knows your using tor. If you access tor from your home computer then your isp knows your using tor.
If your threat model includes Advanced Persistent Threats at the nation state level, then they can do Cybill attacks and control enough nodes that they could track you.
