We already have a rule that hardly anybody follows.

"Do not derail the Rule Violation Threads with irrelevant nonsense or internal disputes. It is solely for making serious, warranted reports of violations of the SiteDiscussion, and Editing Rules, and not for discussion or side comments. Such posts should preferably be removed by the staff, and if a member continues to derail after being repeatedly told to stop, this will result in a temporary ban."
