Just ask http://imdb2.freeforums.net/ admin. He is enforcing his version of rules to abide to, and his moderators are enforcing it. Trolls who are willing to suck his dick are encouraged to post and are promised mod positions. I hope Moviechat moderation doesnt result in similar disaster.
I think it would be impossible for a select group of mods to police the entire boards (if it becomes very active). Mods can be well intentioned, but without relying on user feedback, can give the impression of being dictatorial. I think Moviechat members should have the ability to flag posts they deem offensive or off topic, which will alert the moderator to review the post(s).
When users click on report, do they have to give a reason? Perhaps having a drop down menu will be helpful, since certain trolling is worse than others. For example, instances of abuse should be given higher priority than to off topic posts.
