What would happen if you spent the entire day on Tor at home? You have TAILS and everything but you're just logged on all day or you leave it on just for the hell of it. What kind of legal trouble or suspicion could this raise? How would the ISP know or who would they tell? I think it's not the big of an issue, but with the new law into place where the FBI can get a warrant for any computer using Tor, it's a little scary. Are you still protected if you use Tor a lot from home?
You turn into a onion.
