Not really, to a degree, EVERYONE uses the internet including those types of people, but it's not like there's a craigslist for the dark web that you can just google search. It's a lot of link from one site to another, to another, hidden URLs, hidden messages, some people use code hidden in seemingly normal sites, some of it is knowing people who already know the way to access certain places. Some of the 'dark web' is blatantly in front of people, like the rumor lately about how furniture was listed on a site, for quite a high price, that had code words as 'item labels' that if you searched would lead you to pictures of young girls. Sometimes stuff like that leaks out of the deep dark web, but remember that there's much worse shit the further down you go, and I don't recommend it, because hackers and hitmen are easy to stomach, people hiring rapists/people to maim and torture others is less.
