It's not my place to criticize the way she uses the apps. If that's what's making her happy, then I'm happy for her.

It does sound as if she got "gamified", taking pleasure in the app giving her pings. Such things afflict most of us in one way or another (including me). I suspect she'd find it more satisfying to seek out thoughtful men who are interested in her as a person -- but like I said, she should do whatever she wants.

My understanding of women's take on dating apps is, of course, heavily informed by the fact that they were usually dating me, and selected for that.
