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.
On a serious note, if I’m not mistaken, most cases of Tor users identity being uncovered is via information the user either unintentionally leaving information public, or privately told another user, which was made public due to a betrayal or a security breach.
In most other cases involve security flaws in Tor clients not the network, again if I’m not mistaken.
