Do you have a moderation policy on your forum? If so, is it detailed to every possible rule infraction, or is it very vague and allows moderators a lot of flexibility? There are definitely pros and cons of having both types of moderation policy, but I myself tend to have one in the middle. While it's important to have most things covered to ensure all members are fairly dealt with, your staff should also be able to have some flexibility. What about your moderation policy?
