There are of course legal activities happening there as well However, because I have never bothered to get the software that allows one to go there, I am speaking mainly from what I hear about it, not firsthand knowledge. Just not willing to accidently fall into some website where I might be entrapped in some manner by law-enforcement. It just makes no sense to venture there.
I understand the DuckDuckGo does allow you to go there, but I have no interest, or knowledge how to go there via that search engine. Too old to go to jail. 👍 😋
There is a lot of "nefarious activity" happening everywhere and you think giving government, the greediest, most corrupt and murderous force on Earth, spying powers on everybody and everything will fix it.
You're either evil or stupid or both.
From that stupid statement alone I can tell you have no idea what the "Dark Web" is.
Prove me wrong.
