as i said before, tor is completley safe and untraceable EXCEPT for the tor 'onion router' exit nodes, the exit nodes of tor (where your computer go through their network in order to keep you anonymous) your computer will enter tor, go through multiple systems until they go to the site or server that your trying to locate. now. when you do locate the server, ALL OF YOUR INFORMATION and your computer go through someones 'exit node' in the tor network, that person the one in control of the exit node (in control of the computer system) can see EVERYTHING. your info, where youve been, where your going etc. now with so many people running tor and anyone can set up a exit node, its not hard, its actually encouraged. but, you could potentially go through their computer and they would be able to see who you are.
this is where it gets dangerous, because, if the govt wants to bust you badly enough, which recently they did this to people selling and using child pornography, so it is true, the FBI did it. what they did was they closed, shut down, or eliminated EVERY single exit node in the tor network that wasnt set up by the government, when i say they shut down every one, i do not mean literally, they just shut down the ones with the most traffic and the routers that have the highest volume of people going through their network in order to get to these bad places with child pornography. So, basically by shutting these networks down, the only way to get to these sites with child porn would have to go through the FBI exit node. and if you did that, well then, say goodbye to your anonymity.... because its most certainly gone...As soon as your network went through the FBI exit node to get to this place you were immedialtey tracked, and then I imagine charged.
now im unsure if the fbi made people shut their networks down or just disabled them themselves using hackers or developers. if enough people ran tor, kept exit nodes open and REFUSED THE USA GOVT TO SHUT THEM DOWN then everyone on tor would be fine, but as most of you know, if the USA govt tells you or a company to do somethng and you dont do it, you WILL be targeted. this is where the danger within tor lies. most people quiver at one sight of the u.s. govt so they will gladly do whatever they are told. sorry if people dont understand this im just trying to explain how tor is not 100 percent fool proof. BUT it is most certainly safe and AS LONG AS you are REALLY REALLY careful you could sell for years and year on silk road and move 100s or 1000s of pounds of any drug and get away with it. its all about how safe YOU keep yourself. after that its just relying on tor to be run with being bullied by the government. as long as everyone who has tor, RUNS AND EXIT NODE, there is NOWAY the govt can get you, now when they set up their OWN node and close everyone elses....well...long story short your fucked lol good luck peace.
