I came up with an idea for forumbuildr, due to all the excessive downvoting. Remove the downvote function, leaving upvote and pbum. Then after a set period of time (let’s say three days), all entries that haven’t received more than that week’s median of upvotes are removed. For example, if the highest-voted item in the period has 20 upvotes and the lowest has zero, then everything below 10 will be removed on that day. I hope that makes sense.
