Here's something people have been asking for: An infractions system. It is released as an "Addon". It seems to be entirely about modifying existing code. http://xenforo.com/community/threads/xfb5-xfr-infractions-v-1-0-2-en_ru.9601/ (of course this one, has files and code modifications.) Q: would this be better referred to as a "Hack" ? vs. Addons where they don't require core code modifications ?
