People don't want to call out exceptions and antagonize them cause they don't want to get killed or hurt or get a bad reputation, even if the exception they want to target is truly doing something ridiculous.
Right, here's something that really hurts the situation of trying to enforce the docs on the IC, player-side of things.
The exception you want to attack for his exception has friends. Or even, A friend. Game over man, game over. You might have friends too, but not online reliably at the same time, etc.etc.... damn, that elf who has like two human friends really seems like a powergamer, and he's online all the time. Add to that his stealing and his permahide... f*** me, I'm just gonna let it slide this time. And that time. And all the next 1000 times I see this guy hanging out in my favorite tavern.
Yeesh. What a nightmare. It's like high school with cliques all over again.
