I was sad to read your post. You have given so much of yourself and helped so many people with your insightful and always great advice. You have lived your advice. That's why you are good.
All moderators are NOT like the one you described. Curezone could not survive if all the moderators acted like that. Please accept my apology on behalf of the other moderators because we all are hurt by the actions of one. We don't like it, either. As the old saying goes..."One bad apple spoils the whole bunch."
Please reconsider and stay. You will help many more if you stay.
