On the topic of fighting shitposts, what I would love to see is a button that lets humans (with >= 500 earned merits) mark a post as "redundant":
I can think of plenty of users with >500 merit who would quite happily abuse this and brigade another user's posts to have them all hidden, especially in the case of trust disputes. Also, such a feature would undoubtedly be misunderstood and used for posts the user dislikes or disagrees with, not just posts which are redundant.
