Keybuster.com : how does it work ? 

A key is created and activated by a developer and stored in Keybuster's database.
Any application can now access the key. 

Based on several checks, a client that requests a key will receive a 'denied' or 'granted' as response. 

If it concerns a webpage it will be redirected to the pre-defined page. 
If it concerns other software it will react on the information received appropriately.
