The role of the moderator is to ensure that all comments adhere to the explicit conditions of use and it is their responsibility to remove comments that breach these rules. There are two main options with regard to moderation: pre-moderation and post-moderation. With the pre-moderation all comments are sent to a moderator who decides whether to accept them based on the conditions of use, with post-moderation all comments go straight to the e-consultation and the moderator typically monitors every 24 hours and removes any comments that breach the conditions of use.
