I found out why they have a disclaimer:
Kewlbox.com - free game downloads
I received an email today (November 16, 2004) from Jason McMinn, Director of technology of Blackdot (whatever they have to do with Kewlbox), who proclaims that Kewlbox games have never triggered the download of Zango. However, I know for a fact that Santa Balls had Zango tag along for the download at some point. There was a screenshot of the Zango download with that game which was posted on a discussion board in this thread. I am willing to give Jason McMinn the benefit of the doubt and take his word for now that Kewlbox has cleaned up its act and no longer "promotes" any spyware with their games. IF anyone ever downloads a game from now on at Kewlbox and ends up with spyware, please email me and let me know right away.
