I think....The person your talking to is either a blizzard employee/employer.
or is related to a blizzard employee/employer

Cause' cursing in public/party/raid/msg...wat ever usually don't get any penalty (barren's chat pre-BC) unless the person is taking things personally.

Player's who report usually will get informed earler for the awareness of the incident and NOT a direct "bann/suspension". Besides this is a very small matter.

I strongly suspect whomever you scold was relater or IS a blizzard employee/employer. SO you face the music. haha

or u played WOW in a cybercafe that has a keylogger,one of the reasons why i nvr feel safe to play WOW in a CC.
