In discussion and events, moderated describes environments or sessions that are guided by a moderator who enforces rules, manages participation, and maintains civility. Moderated discussions aim to balance viewpoints, prevent derailment, and ensure orderly dialogue. Moderation can be applied before or after a post or contribution, with terms such as pre-moderation (review before publication) and post-moderation (review after publication). Online platforms often employ moderation to enforce community guidelines, filter content, and handle disputes.
