Ok but, if you're gonna go through the trouble of swiping left on everyone AND remembering their faces... Why not swipe normally on the people you like and just let the thing do its work ?
Tinder. Thats a screenshot from a Tinder conversation. Swipe left means 'not interested', swipe right means 'interested'. If someone you swipe right on, also swipes right on you, you get a 'match' and you can chat with them.

If you see the same person twice it means they swiped you right.
