No, it stems from the imbalance in demographics. If a man and woman both swipe right on 100 people, she'll get a lot more matches than he will.

The only thing she can do differently is swipe right less, and then you're going to have guys complaining that they hardly ever get a match. They'll only be swiping on 9's and 10's. If your personality is doing all the heavy lifting, this would make dating sites unusable.
