I sent a friend of mine about 2000 Yo's (Charles will show you that the Yo app uses Parse...very simple API requests) with Charles's request-replay feature - quite easy to do and oh so funny...or at least I thought so.
Wow, didn't realize. That said, it's functionality is very limted, requires an API key, requires people to subscribe to you, and likely has rate limits - none of which are problems if you just pose at the Yo app and use private APIs.
