Various other aspects of the design of TOR make it even harder to penetrate. For instance, there are now frequently multiple middle nodes, spread across the globe, adding legal issues as well. The "exit node" can be anywhere in the world, as can the middle node, requiring any investigation to obtain warrants internationally. TOR also has "hidden services" which themselves connect to the internet via a TOR protocol. While a "hidden service" can still be hacked, each service must be hacked individually, ensuring that only sites with illegal content and a large audience are taken down.
The strength of Tor also leads it to be very slow compared to normal browsing. It is generally fast enough to download large files within a few hours and stream videos without pause. Whenever a user uses Tor, he slows down the network unnoticeably slightly for every other user. People who download large files for immoral purposes unfortunately slow down Tor.
