Nevermore own this website together with Pwizard. So he can do whatever he wants. Besides, this game is wasting space on a "reasonable" fact. You moderators could post multiple times as you have the power to delete every post you have made compare to us, non-moderators. So, there's the logic.
And this game is only based on the fact that it's considered a feat to get 20 posts in a row before one of the eight moderators gets online to ruin it. We haven't deleted the old topic, and if space was an issue, the 5000 topic would have been a 500 topic.
