It's interesting to see the flipside of this (he said, veering wildly offtopic). On OKCupid and other dating sites there is a particularly style of picture many girls use, cropped but obviously they're with a male, like his arm is around her or something. Projecting female values, they think they're saying "look, I've had a boyfriend, that proves I'm not crazy". Unfortunately the message received by a male is "she's not over her ex".
