I couchsurfed throughout my 20s and it wasn't uncommon to hook up with the host/guest if they were cool. Any app that's geared toward meeting people is going to be like that, regardless of one's puritan views. That's exactly part of the human connection that the site is intended for, like it or not.

It's no less of a potential hookup app for women as it is for men. You don't think women want to me interesting guys to fuck? Else women wouldn't even stay with men. They already avoid the guys with bad reviews.
