Use a "Discussion Closed" flag for closed forum discussions if they remain unanswered

I support the policy of closing older discussion threads on this forum when they have been inactive for a while as they seemed to be becoming targets for AI-generated spam.

However, it would be helpful if they were clearly marked as closed with a "Discussion Closed" tag rather than left as "Discussion Open", which is pretty misleading. At the moment the only other option appears to be "Answered" (and for ideas, "Voting Open", "Under Consideration" or "Implemented"), but the vast majority of threads are left flagged as "Discussion Open" whether they are open or not.
