The moderation team act individually and review collectively. It is better to make a quick, reversible mistake than to let bad content sit on the server for want of concordance. Any team member may question the decision of another. When this happens we make a decision as a group, putting things to a vote if necessary. This can mean undoing actions that were taken, or taking actions were none were taken.
A variety of opinion is a strength of value when creating long-lasting communities.
When something feels wrong, it is best to let your perspective be known. "I think x because y". Your perspective is valuable.
User moderation is based on observation of the server rules as interpreted by the moderation team. The rules are deliberately concise. The moderation believe that an exhaustive list of what is allowed and not allowed has not been shown to be necessary where members of the community are acting in good faith.
