We are NOT as privacy-illiterate as we are made out to be in recent articles about Girls around me. For instance, I recently applied to YC and enlisted my Facebook profile. And, I have been posting a lot of public content with that very intention in mind for months now.
I came across another instance of this when I was trying to "teach" my sister the importance of heightened privacy. She plainly refused as she often needs to plan open events and she needs to put up a lot of her information public.
We need to understand that just as you cannot ask women not to go out for fear of stalkers, you cannot ask people not to share information publicly. In fact, we need to keep up with the shift in social media to increase law-enforcement. Girls Around Me is a clear violation of the intention with which millions share their information publicly.
I think we need to standardize and associate User Intents as a first class attribute to a user's data. And find and penalize miscreants like Girls Around Me who violate the intention associated with people's information.
