Things you need to know about Dark Web
1. TheDark Webis not an Iceberg (they does not have levels), the only you need is a good WIFI connection and the Onion Link to enter to the pages.
IS NOT LIKE THIS ^
2. TheDark Webcurrency is the BitCoin
3. Even if there are pages of rape, murder,people and organs sales, it is very difficult to find it, you should look for much and spend many hours of investigation to find these pages.
4. The Onion(Tor Browser) is not monitored by the police or the FBI, there are some pages but they are "scams"
5. Onion is not the only browser to enter to theDark Webbut it is the most used Browser.
Good!
Police definitely do monitor darkweb activity. They outsource it to analyst companies. I know this due to my job searches in London for blockchain companies, there were an overwhelming amount of darknet and bitcoin monitoring positions available.
The CyberPolice checks Dark web, but only certain pages
They aim for what they can get to, essentially. I agree, it's not impossible to be totally safe. For now.
Beautiful post
