I'm not sure which mod you think is biased (since we know it's not me or my alter), but if you think he has some ulterior motive when he gives advice- then don't listen to those posts.
a set of rules is difficult, as digger said, because it means that the people who need them, will also try to find loopholes in them.
Most people don't really need a set of rules to follow- they know common decency and if they step outside the unspoken set of rules once in a blue moon, it's not so bad as the guy who is constantly looking to do it just because he can.
