@Dark Cloud Aight. Just saying I've seen this happen a lot before in other groups. Someone gets the bright idea to act a bit brash, and the impact of their actions affect more people than they think. Usually what happens next is the offender claims that they had permission to do whatever it was that was causing a problem, which basically means anyone who are bothered can basically get fucked. This leaves a bad taste when it feels like a DM basically allows someone to be an ass and get away with it. Grudges are formed. Or people just leave.
I've seen it happen at least seven times. Four times in RPGuild itself. I try to learn from those experiences and nip that bud real quick.
Incidentally examples like I just said also tends to happen historically, with knights and such. They get permission from their lords to do something existentially "okay", like dealing with bandits. In the process the knights start shaking down the peasants and merchants, taking stuff, and generally being hostile to everyone they think might have something to do with banditry. Now the peasants don't like them, but when they try to appeal to their local lord they basically get told the knights are allowed to do that. This creates hostilities. That's more or less where Domic is coming from.
