The FBI has reportedly seized the sex marketplace website Backpage.com, according to a posting on its website on Friday. "The posting said the U.S. Justice Department would provide more information at 6 p.m. EDT," reports Reuters. "It said U.S. attorneys in Arizona and California, as well as the Justice Department's section on child exploitation and obscenity and the California and Texas attorneys general had supported the work in shutting down the website." From the report: Lawmakers and enforcement officials have been working to crack down on the site, the second largest classified ad service in the country after Craigslist that is used primarily to sell sex. The U.S. Senate passed legislation last month making it easier for state prosecutors and sex-trafficking victims to sue social media networks, advertisers and others that fail to keep sex trafficking and other exploitative materials off their platforms. The Supreme Court in January 2017 refused to consider reviving a lawsuit against backpage.com filed by three young women alleging the site facilitated their forced prostitution. But the site has since then faced a slew of other lawsuits alleging child sex trafficking. According to AZCentral, local FBI officials have confirmed "law enforcement activity" Friday morning at the Sedona-area home of Michael Lacey, a co-founder of Backpage.com. The raid comes amid what appears to be a shut-down of the website.
