That's because in game you can quite literally cop a ban for cut and pasting NPC dialogue if someone reports you over it.
I still laugh to this day at an old friend eating a temp ban in a dungeon for politely asking to be kicked as he had a raid starting shortly that he didn't anticipate and got reported for it. Doubly ironic as that was probably one of the few times he was actually ever polite =(
Here on the boards, the stakes aren't as high (Can confirm, you don't lose your character in game if you take a ban here), the rules and lines are much more clearly defined and overall the moderation would appear to be much laxer with things seemingly taking a sizeable mass report to get acted on perhaps the Mods here are kind of inconsistent in how they tackle posts that go past what's acceptable.
