Pornhub is awash in lawsuits. Unverified videos still on the site could bring even more, says the author of the new book 'Takedown.'

• Hundreds have sued Pornhub, saying videos of their abuse remained online despite their protests.
• Age-verification requirements for Pornhub users in 19 states will be weighed by SCOTUS this fall.
• The site's many unverified videos will bring more legal woes, warns anti-trafficking activist.

It took just a few minutes for anti-trafficking activist Laila Mickelwait to log on to Pornhub, type the search term "homeless," and find a disturbing amateur video, the kind she complains about in her new book, "Takedown."
