WAM is based on a variety of measurements, including page views, contributions, and level of user activity. We can't supply an exact method since that could lead to people gaming it, and because those rules would likely get tweaked anyway. Does that help?
I am one of the bureaucrats on the Gravity Falls wikia. Terrios528 told me that he has been communicating with you about the current topic of bureaucrat demotions. I had asked Terrios528 if I could speak to the wikia staff member so I could get a chance to tell my side of things, and he directed me to you.
Is it possible to talk in a more private setting, such as email, rather than on your wall? I ask because although Terrios528 is keeping me up to date with details in your communications, the exact messages are not public. I would simply like the same courtesy.
