Hey, mods have to be able to trust other mods. We have the power to lock each other out of forums, undo spam deletions, turn all posters into the night of 1,000 mods, even delete each other's accounts in some cases, or something as simple as change each others' usernames or passwords so their usual login credentials no longer work.
Not that you needed to know that, but when the trust goes and it becomes mod vs. mod, everything on these forums -- and I mean everything -- can easily go down the toilet in a hurry. And believe you me, nobody wants to be around to be a mod under those conditions.
