PROPUBLICA - Dec 2 - Match Group screens for sexual predators on Match, but not on Tinder, OkCupid or PlentyofFish. A spokesperson said: "There are definitely registered sex offenders on our free products." Match first agreed to screen for registered sex offenders in 2011 after a lawsuit. A Match Group spokesperson said the company cannot implement a uniform screening protocol because it doesn't collect enough information from its free users, and that background checks do little more than create "a false sense of security" among users. "Our checks of the sex offender registry can only be as good as the information we receive," she said, explaining that the government databases can lack data, have old pictures or include partial information. Herb Vest, founder of dating site True.com used to pay ~ $1M a year for third-party services like rapsheets.com and backgroundchecks.com. True.com even warned subscribers that the company would sue if they misrepresented their pasts. True ultimately folded in 2013 but Mr Vest insists the cost of doing background checks didn't play a role in his company's closing. "People can't rely 100% on the sites," Vest said. "But as an industry, we could have done much better."
