I know the rules are already defined, but I think mason should be able to freeze novice, novice have been griefing and shttalking in chat for some hours now and there was no admin on. Mason take like 20h of play without a single act of griefing, and there is alway at least 1 mason online at anytime, this could help reduce griefing (in main) alot, and also encourage novice player to build better structure. Well, just my opinion.
