It's no longer determined by your swiping behavior, but rather who swipes left or right on your profile, and their elo.
If you only get swiped right by people with a low elo, then your elo will drop and your profile will only be shown to people with a low elo.
Vice versa, if a lot of people with high elo swipe right on your profile you will receive a higher elo and be show to profiles with a high elo
If it was determined by who you swipe right on it would be too easy to game the system
They still do that, and it's no secret.
