I gave your more then just "buttons", you practically my theme entirely and made a few changes. Technically by using resources from my theme, you are violating the Creative Commons Attribution-Noncommercial-No Derivative Works 3.0 License
. The license states that you cannot modify or use my work for redistribution or for commercial use. In this case, you are both redistributing elements from my theme (color scheme, buttons, etc.) and you are using it for commercial use (by directing users your sites which has ads that you profit from).
I would like to lay down some policies and prevent such things from happening again.
