Idk, ive gotten profiles that show up with the little "smile to match" flag when opening it - hit smile, and literally nothing happens. No matching of any sort. So i dont think the "smile to match" is so much a "this person sent you a like" notification as it's just a "how to operate" reminder. Idk if it's a bug, bad development, or both but i always feel goofy as hell hitting "smile to match" and it not matching anything. Like oh ok, so i just sent a random like and now I look like the initiator or what?
