In this repo are some of the rage faces used by the fffffffuuuuuuuuuuuu and memebase communities, and, of course, 4chan.
The lulz license. These examples of use may or may not give you confidence in using the rage faces commercially or non-commercially:
- There is a Rage Faces for SMS app in Apple's App Store. It made it through their stringent approval policies and has been there for months. It's a free app, but the owner has other apps for sale that can be accessed from the app's page in the App Store.
- The Cheezburger Network, which recently had $30 million invested in it, is using Rage Faces to make advertising money.
