I’d like points removed for new threads and any thread/reply counts. That means it’s same to reply as to make new thread, so new threads being dumped to the top of the view created by people to get high on leaderboard is reduced.
It then becomes logical to reply in the best matching thread rather than create a new thread to just farm points. Then a thread can become one you get notifications or not so folks can focus on their interested topics.
I agree to not have a prize based on maximum participation will increase engagement. As the “no point bothering” argument the leaderboard creates is removed.
