I have received only two post reports in the last week, and one of those was me testing that my spam filter wasn't catching them. I've noticed that while many users have observed problem posts and has pointed it out, they haven't used the post report system. In future if you find a post that breaks the rules please report it using the button or depending on your skin. In future if I see users replying to such posts without reporting the post I will give them a warning. If they continue to do it they will receive an infraction.
