Talking about gold selling in game

[Pepito123]

Hello guys. I'm planning on selling gold in tbc and my friend accidentally said in a group chat (only both of us in it) "how much gold do u want before start selling?". I am worried now this might trigger an alarm for Blizzard or something. Should I be worried?? Does Blizzard have a system to automatically detect and flag words like gold and selling or whatever?
