I'm sorry you've had bad experiences from mentors. If you feel harassed by any in whatever sort of way there is a report option available and the GM's can go over chat logs. I personally as a Mentor stay out of Novice network. I've ran into a similar issue with a mentor before that was disrespecting people and I had them removed from the Novice Network, only to be removed by them from an ALT account they had still in there. It's not shocking but if you ever need questions answered, novice network is not best option to use.
