Simple solution, Blacklist people that upset you.

Try reading the message when you join the Novice Channel, (Don't agree, don't join) which you clearly must know. And by the way, you don't need to be in the Novice Channel to be a Mentor and you know, help new players, so maybe give it a rest and offer your services in the starting Cities or something, anything but waste Support Staff time with your personal rants.

Also try a Search of "New Adventurer" or "Returner" status, because lots of them wont go near the Novice Channel for their own reasons.
