The book has been closed on Backpage.

Federal authorities on Friday seized Backpage.com, the classified advertising website long suspected of selling sex, and charged at least one of its co-founders in connection with a human-trafficking investigation.

Backpage is now dark, replaced by a notice about a federal operation including the FBI, U.S. Postal Service and IRS. "backpage.com and affiliated websites have been seized," the note says.
