The IP address you're posting from was recently used to violate the Battle.net Terms of Use Agreement - http://www.battle.net/tou.shtml. The most common cause for this is connecting to Battle.net with an invalid CD-Key, followed by spamming the chat channels, use of flood or load bots, harassing another user, and/or the use of a third party program(s).
The IP address has warranted a lengthy restriction and will not be able to access Battle.net (Lordaeron) for another 12 days from now.
