I created a thread about this a while back, but in replying to other threads on similar topics, I've refined the idea, and decided a new thread was warranted. There are three types of necro-bump: malicious, accidental, and genuine. An ideal forum would minimize the impact of malicious and accidental necro-bumps, while allowing the genuine ones to bubble up to the surface. I think this can be accomplished by adjusting the way threads are sorted. First off, give people a sort where there's no bumping at all. If we changed the "Latest" sort to be based on the created on date of the thread, rather than the last post, it would turn the sort into a pure chronological view of the forum; there would be no bumping. Next, we need a way for active threads to stay above inactive threads. This is where the "Trending" sort comes into play. If it were changed to be what "Latest" is now, but rather than using only the created on date of the last post, it used an average of the last X posts, it would allow active threads to stay on the front page, while giving new threads time on the front page to become active. It would also prevent a single person from necro-bumping a thread, while allowing a dead thread that genuinely becomes active again to resurface to the front page. The question becomes, what should X be? This is where I think the popularity of a thread should come into play. Start with some number, 5 for instance, then adjust that number based on the number of likes and dislikes the thread has. Dislikes increase X, likes decrease X (not below 1). This way, popular threads are easier to bump than unpopular threads, and if a thread does manage to get bumped incorrectly, it can be reburied via disliking the thread. Thoughts?
