No longer technically an unposted rule.
Site-moderation:
Rarely self-moderation isn't enough; e.g. threads which share information on a private / anonymous / gunboat game, or threads about suspected multi-accounters / meta-gamers / bugs.
These have a negative impact on games which self-moderation can't prevent, so the mod team can lock/silence these threads:
Silences can apply to a user or a thread.
The details can be viewed on the forum page, when the "New thread" button is pressed.
Thread silences last indefinitely, but user silences expire after a brief cool-off period.
Silenced threads / users can still be viewed, however no more messages may be posted.
Silenced users can still play in games; it affects the forum only.
Remember that mods will only silence users / threads when there has been a clear rule violation, as a last resort.
If it's a first time mistake, and you inform the mods that you won't repeat it, they will probably be happy to reduce your cool-off period!
Don't create new accounts to work around user silences, or post threads to continue on from ones which have been silenced! This may result in bans etc, which would be worse than simply keeping off the forum for a few days.
Thanks for helping keep the forum from negatively impacting peoples' games!
