I would like to respectfully suggest that this procedure might be over moderation. And, as you said, it's lots of unfun work. Not sure what you mean by statements about space. Disk space is cheap. I have seen many occasions on other forums when threads, even years old, can still have value, particularly when they link to resources. Taking the National Association of Watch and Clock Collectors ( https://mb.nawcc.org/
) forum as an example, they have Threads 178,823 / Messages 1,568,431 / Members 53,992. Granted they have about 50 times our membership and probably more moderators. But, I don't have any evidence that they do large amounts of thread locking and purging. I have replied to threads that are years old if I can add something useful, assuming that the interested parties will get a notification of the update. Granted, clocks and watches may have more staying power than security topics. But, new and updated threads automatically bubble up to the top of the what's new list. The longer a thread is ignored, the lower down it goes so it may end up on page 20 or something. But, the content is still accessible via search. Everything is largely automatic, and I'm guessing the moderators can focus more on the fires that need putting out. I realize that y'all don't generally want overly religious, political, sex, very controversial topics, profane language, illegal things, and cat fights here. That's understandable, although security often intersects with controversy, politics, and privacy issues. So does health, one of @Steve
s pet topics. So, if things get out of hand, the moderators can jump in. Spammers hocking non relevant products or weight loss or mortgages or whatever should be put on pre moderation to post, warned if needed, then bounced. People posting active links to malicious sites, as opposed to neutered information links, could be bounced immediately. That's not the same as minor etiquette and procedural violations. Letting message flow and sorting be automatic might make your job much easier. Threads could be auto deleted after years, not months. Maybe 5 years. If they keep getting traction, they keep bubbling up to the top and the timer resets. I've seen threads with 100 pages of messages. And, threads that have enduring value could be made sticky and or locked to prevent deletion even if they're not updated often. Unless we do get in a cat fight or become abusive, you shouldn't have much to do. Just something to think about. We DO appreciate the efforts to keep the forum clean and functional.
May your bits be stable and your interfaces be fast.
