I know, but Twitter.com will be the same website if you use Tor or not. Since freedomhosting went down, CP has been significantly reduced on the Deep Web anyway, although there is still a lot.
My favourite story about the deep web is the guy that takes young orphan girls and turns them into human sex dolls. It's freaky af and makes me ill everytime I read about it.
If you start on the Hidden Wiki, all illegal pornography is labelled. Everything you have read about the deep web will be on the Hidden Wiki, and it is all labelled. For example, for Bitcoin services - there is a Currency section.
Unless you're a retard it's extremely hard to click on the wrong things.
