Check out the link below and be learned. Warning: The National Security Agency (NSA) and other authorities monitor who visits Tor's download site and especially those who download the Tor Browser. Articles have been written about this. Of course, many, many folks have been downloading Tor regardless. Tor is not as anonymous as most folks think. World authorities who track terrorism, weapons dealers, and illegal content like underage material try very hard to catch users on the Tor network. Software failure and human error are the two biggest reasons why people end up under investigation for their online activity. Again, only you have to answer for your actions if you get caught doing illegal activity online. There are many You Tube videos that introduce you to the Deep Web and Dark Net, the do's and don'ts, and the ugliness that exists in that part of the web. Check them all out.
You've been warned! You can never say no one told you to stay away, because I'm telling you to stay away! You don't need to go there. There's so much to see without having to go the Deep Web and Dark Net. Curiosity can and will get the best of you. Remember that when images and video end up on your computer. Windows has a high failure rate, and many, many folks don't realize that images, videos, and links can get saved without you knowing deep in your computer's Registry. Windows loves to hide things. Remember too...how well do you know your friends and online contacts? If you exchange material from the Deep Web or Dark Net, your computer becomes a storage device. Too many folks forget they're using Tor, and accidentally save illegal material on their hard drives or flash drives. Then someone else finds the material. If it sounds like I'm trying to make you paranoid...I am! Good luck and happy curiosity.
