I have not been on the apps in yearssss but based on comments from female friends and colleagues who are, the men post pictures from over a decade ago when they were 25 lbs or more lighter, hairline still existed -or- post pics with giant fish, group pics and you can't tell which one is them, or them with their kids to appeal to women looking for a "good father" (totally weird to me to put minor children on blast like that but whatevs).
I have another story to tell y'all. I'll come back in a few. I have to send some ish to the people in purchasing.
