Need a Call of Duty DDOS Tool?

Found an article today about a teen in UK who was arrested for selling a Call of Duty DDOS tool on a website.  
"The youth is currently under arrest and is likely to be charged". 

I most be of an old school, but what does booting people off servers accomplish, is that like the ultimate headshot?,  I presume the 'youth' is playing the game and  if he's not able to beat them within the game, he beats them outside the game.   Moral of the story is -  if you are going to try to cheat, don't charge others for the privilege of cheating too.
