There is more to this then meets the eye. This kid was not just using the tool but SELLING the tool and he possibly MADE this tool. And by tool I mean a denial of service ping bot. Which was no doubt aimed right at Activisions authentication servers. No wonder they were pissed.
This is not either in the Blues News post of the linked article. Its not just a kid kicking people off his server. He was making money selling it.
Funny how the article is written to hide this fact and raise peoples ire. You guys took it hook, line and sinker.
