Couple quick notes:

1. New adventurer status controls more than just whether you are eligible to be in the novice network or how other players elect to mentally categorize you. It controls a 20% XP bonus when grouped with a mentor sub-20 (including level sync). It renders you eligible for free aetheryte pendulum teleports. Bullying people into removing the status to avoid being harassed is most definitely not the answer.

2. The novice network is subject to the same rules enforcement as any other chat channel. If there are trolls there, report them to GMs. Also note that kicking someone from the novice network doesn't magically do anything. You have to actually report them yourself. There's zero proactive follow-up on a kick.
