I'm very skeptical. No doubt Snapchat is game-ified somewhat, but I have people aged 12 to 53 (and all ages in between) snapping with me and not a single one of them has ever mentioned their snap score. I'd bet most don't even know their score.
Trophies aren't really all that unlockable. Within the app, any trophy you haven't unlocked is a lock icon with ??? underneath it, so you don't even know what you need to do to achieve it. You can go online to find out, but neither my 12-year-old daughter nor my 17-year-old sister have bothered to do it. They just don't care. That's not what it's about for them.
