Suppose I send death threats using Tor. Then, I send update again. Victim says it is me. Police checks logs on the server and at my ISP. The IP addresses do not match since I used Tor, but there's logged Tor traffic from my laptop which correlates with what was found on the server and at my ISP. And even worse, it happened twice, since I've sent two messages.
Can this be used in court as only evidence?
