While I certainly can't deny that there will always be 'those users', I can tell you that anyone can report posts and our Insights tool will help Admins and Mods sort reported posts out pretty quickly. The 'reporters' are tracked as well, so after approving or deleting reported posts, users who are doing any kind of false reporting will stand out. I can help with any questions regarding Insights, and if you need additional help with Moderation (let's say/hope Discussions explodes with users!) we are here to lend a hand. Just let us know.
