An algorithm developed at Carnegie Mellon University makes it easier to determine if someone has faked an Amazon or Yelp review or if a politician with a suspiciously large number of Twitter followers might have bought and paid for that popularity.

The method, called FRAUDAR, marks the latest escalation in the cat-and-mouse game played by online fraudsters and the social media platforms that try to out them. In particular, the new algorithm makes it possible to see through camouflage that fraudsters use to make themselves look legitimate, said Christos Faloutsos, professor of machine learning and computer science.

In real-world experiments using Twitter data for 41.7 million users and 1.47 billion followers, FRAUDAR fingered more than 4,000 accounts not previously identified as fraudulent, including many that used known follower-buying services such as TweepMe and TweeterGetter.

Bad news for the nascent astroturfing industry.

    I'm going to vote for Trump, but that's because I hate the Clintons and the Establishment they're part of. Normally I'm a progressive and would much rather have been able to vote for Bernie.

    That said, on the 8,500 mile roadtrip i took around the country this summer, from New York to Whidbey Island, to the Bay Area through the Southwest and then across the South, i couldn't count the number of Trump bumper stickers, billboards, and yard signs i saw. Even in the bluest of blue areas like Seattle, Portland, Eugene, OR, San Francisco, and Madison, WI, i did not see a single sign fof any kind for Hillary anywhere. Bernie stickers and a couple for Jill Stein, the Green Party candidate, but none for Hillary. Finally in Mesa Verde i saw a guy with a Hillary shirt on. He turned out to live a couple blocks away from me in my Brooklyn neighborhood and worked at her Brooklyn campaign HQ.

    That's a massive enthusiasm gap. And the more Wikileaks stuff that comes out and the more of her corruption that comes to light, the more it's going to suppress her turnout. Everybody knows that Americans mostly don't pay any attention to the race until the final 4 weeks, so all Trump has to do is run a "Morning in America" campaign, braced up with some Willie Horton attack ads and he'll win by a substantial margin. As it is, Hillary has massively outspent Trump only to see her lead in the polls evaporate.
