It hides your profile from friends, business contacts and co-workers, and only gives you up to 5 potential matches per day who you can say yes or no to. I found the most catfish-y profiles on Tinder, including one guy who lied about his age and confessed he was "old enough" to be my father.

You download the app, create a profile, add some of your favorite pictures, and write a short bio. The League is the worst. You have 24 hours to talk to your matches otherwise they will disappear into the internet abyss once and for all.
