Quitting games on Call of Duty: Black Ops can get you penalized, but forcing other people to quit games can get you locked up. A UK teen is now well aware of this as he sits behind bars for using a program called "Phenom Booter" to kick players from Call of Duty servers in September. 

The Phenom Booter program attacks servers, denying specific users - or all users on the server - to be booted off the server. This hack was floating around on forums earlier in the year, and can be seen in demonstration with a quick YouTube search. E-cops eventually traced the attacks from the teen to the Greater Manchester area, charging the 17 year old with violating the U.K.'s Computer Misuse Act of 1990.

"Programs marketed in order to disrupt the online infrastructure not only affect individual players but have commercial and reputational consequences for the companies concerned," stated Detective Inspector Paul Hoare to BBC. "These games attract both children and young people to the online environment and this type of crime can often be the precursor to further offending in more traditional areas of online crime."
