As a supplement to my thread here.
Looking at the D&D forums, they also have a little forum culture where they start granting themselves rights. Like 'Oh, the GM can't cheat' and such. And they have a thread where they all agree with each other that that is the case. And 'thus' it's the case for their group. Except it's only the people on the forum who have agreed with that, not their own group.
