Well in reality it isn't very clear. A "select few" moderators is intentionally vague, since we're not sure who you're talking about, we're all left with the same impression. Mod warnings are not meant to abuse some sort of power or flex some sort of muscle, they are intended to try and lower the temperature or try to get conversation back on track without handing out warning points, which we'd rather not do. Talking in generalities like this isn't overly helpful, I suggest if you have an issue with any action by a moderator that you contact one of us with it personally.
