As it has been announced on the main meta, diamond moderators now have the ability to remove questions from the Hot Network Questions List.
Since the policy on what to remove seems to be on a per-site basis, the same post also recommends the creation of a meta discussion with guidelines for both moderators and general users on when a question should be removed.
With this intent in mind, what criteria should be used for removing a question from the Hot Network Questions? When, if at all, should users be flagging questions for moderator attention for this removal?
