Facebook.com’s Graph Search
What it is: A search engine that finds photos, similar interests, and other information about the site’s users.
How it works: Instead of listing links, it combs information using real language, like, “photos of Bob Smith on New Year's Eve.”
How women use it: “[Women] can find all photos [guys] are tagged in, even if it is not on their wall,” says Jason Silver, president of We Just Match, a personalized matchmaking service. “The first thing I look at are people's pictures. You can see what they're doing, how they dress, and who they surround themselves with.”
Try it: Search for yourself. Type in your name, a category of interest such as photos, and a location.
What it is: A no-fee database of sex offenders in the United States (with the exceptions of Nebraska, New Jersey, Rhode Island, South Dakota and Vermont).
How it works: By typing in a first and last name, (zip code and middle name are optional), records of offense are at her disposal. “The site is a gold mine of information, complete with photos, physical descriptions, the type of crime someone committed, weapons used, home address, whether the victim was a minor, and much more,” Coder says.
How women use it: If your name pops up, she'll stop answering your calls. “There is no advantage to appearing on this site,” Coder says. “You don’t end up listed on a site like criminalcheck.com if you have a squeaky clean record.”
Try it: Type in your name. Here's to hoping you don't share your identity with a criminal.
What it is: An online tool that determines if texts were crafted by a male or female. It is 60-70% accurate.
How it works: “The words you use can reveal identifying features. GenderGuesser uses an algorithm to try to determine if the writer of a text is male or female,” Coder says.
How women use it: Catfish, anyone? If she has yet to meet you face-to-face, it can reveal whether you're the person you claim to be. “If you have enlisted the help of a paid writer or service to help you woo someone online, this site might ‘out’ you,” Coder adds.
Try it: Find a sample text in your phone. Type it into the system and see if GenderGuesser correctly determines the writer's sex.
