Ignore will cause the game to close. The reason that is coming up "supposedly" is pb is updating the message boxes to reflect what they are really doing (banning the account forever and not for 1440 mins or w/e) so instead of a good looking "your kicked" box.. you see that crap. The string length is pb doing it's job and returnig a value thats higher than it should be = kick.
Then again.... does this look like the warrock helpdesk? Pretty sure there are billions of topics on this on the official forums.
