Is this Hillary trying to get ahead of the possibility that there are videos out there of her doing "horrible things"?

Is that quote for real?

And I love how people characterize "the dark web" as some sinister realm disconnected from the internet as we know it when it's nothing more than a way to access the internet more or less anonymously (you're not actually untraceable, just much harder to trace).

What videos were shared for the 2016 election?

Are videos going to be exposed about Biden, Warren, and Sanders?

Sounds like it.

Yes, it's real. Start at 35:00.

Legislatures call it "dark web" because then they can appeal for more control and oversight of the internet without actually saying the internet, because they know folks will object to the latter. Instead they use the fanciful term dark web to suggest some distinguishable community they can target within the internet. It's also used by security companies to make the internet a dark scary place that requires their services to keep us safe from that part of the internet.
