Ok Cupid's algorithm then uses that information to calculate a match percentage between a particular user and a potential partner.
Unfortunately, small tweaks to interfaces can only do so much if all users don't play by apps' often easy-to-break rules.
This may sound like pure optics, but apparently it's working: "Since we launched the pledge, we've seen decreases in harassment, both from reports and our machine-learning technology that detects harassing language," says Melissa Hobley, the chief marketing officer of Ok Cupid.
"We know that women in particular are really frustrated at how dating apps are set up to be incredibly focused on appearance.
"I'd get messages from men that would say things like, 'Do you want to meet up to have sex?
' And when I'd say no, they'd say, 'Oh, well you're fat, anyway.'" Craig says the criticism would bother her back then, before she'd started her successful fashion blog in 2013, found the body positivity movement, and started embracing her shape. While dating apps are notoriously scary spaces for women in general, with some 57% of female app users reporting some kind of harassment, plus-size women seem to have a tougher time than their "straight-sized" counterparts.
