You shouldn't be one to judge a book by its cover, obviously, but if he's actively trying to deceive people, that says a lot about his personality.

And to be totally fair, physical chemistry is still important.16. If he talks to you constantly but doesn't meet up, or have social media profiles, or ever want to video chat ... Start doing reverse image searches (and don't forget to flip the image in case he's doing the same thing to throw you off the scent).

My very first connection had obscured his phone’s camera so I couldn’t see anything, and all I could hear was his repeated whisper from off-screen: “Hey come suck my pussy.”Monkey was created by 16-year-old Australian high school dropout Ben Pasternak and fellow dropout Isaiah Turner. If two people are enjoying their chat, they can become friends on the wildly popular photo messaging app with just a mutual press of a button in Monkey.

It’s probably worth noting, though, that Monkey’s end user agreement, a short paragraph found in the app’s “legal” section, has multiple grammatical errors in it, and whoever wrote it just couldn’t figure out subject-verb agreement.

Jay, a 29-year-old from Bridgeport, Connecticut, was also just getting the hang of Monkey when we matched up, and he thought it was “pretty cool.” Jay explained that he’d started using the app because he’d gotten a text saying he should.

If he doesn't have a job, it's understandable that he won't want to lead with that, but if he won't even elaborate when pressed, he either (1) does something shady as hell for a living or (2) is just fine with lying a lot.14. It's one thing if he's being a gentleman and doesn't want you to make a long drive out to see him.

It's another if he freaks out at the prospect of you being within a 20-mile radius of his home.15. Either he has low self-esteem, doesn't care about pictures, or that picture is not at all indicative of him.

The first person I actually to on Monkey assured me this was all normal.

“You’ll be seeing a lot of private parts,” Al, a 24-year-old student in London, explained.

He explained that he had gotten to know Monkey’s founder, Ben Pasternak, through Snapchat, back before he “got too famous for me.” Pasternak was fishing for feedback about Monkey, and Al gave him some gentle criticism about the amount of genitalia he was seeing.

Monkey has since added a little policeman emoji in the upper corner of the chat screen, which can be used to easily report and block inappropriate monkey business.

Their app, which has earned them props from Apple’s Tim Cook, already has 50,000 users, and Pasternak and Turner are reveling in success and flaunting wealth. All you see at first is a potential chatting buddy’s age and their country from which they’re chatting.
