But you're using 'dark web' as if it necessarily implies "the worst thing[s]" and "the nasty shit" on Tor. The term 'dark web' doesn't refer to anything nefarious in itself — it simply means content accessible only via Tor (or some other software or network).

Sure, many so-called Hidden Services offer illegal and immoral content, but the dark web is enormous. There are many more such sites offering ebooks and other (legal) media, anonymous blogging/forums/social media, whistleblowing services, censorship-resilient news platforms (BBC, NYT, The Intercept, ProPublica), cryptocurrency trading, and so on.

Hell, even the CIA has a 'dark web' presence on Tor [1].
