That's a tough story. I'm glad you got out of it without any bans.
But I have one general question:

Am I, as an ingame player, required to read the chat ?

After all, you can turn it off by simply switching to the combat log instead. Is it stated somewhere in the EULA that customers have to read what other people write ingame?
Seriously, what if I decide to turn it off, because I don't feel like reading 12-yr olds' comments? Will a GM-whisper somehow pass through anyway? I mean without any addons.

Any thoughts?
