Snapchat made a big mistake due to their marketing department.
The company which made their investors millions of dollars from the release of their public offering of shares early last year just made an error with a release of a game on their platform asking it's users if you want to punch rihanna or slap chris brown.
They were in the news in 2009 of domestic violence and with this one flub have enraged all their users to drop the app.
