The original title is almost double the maximum length for HN titles, and it’s confusingly dry. “Children's Advertising Review Unit” does sound like it could be a government entity. I do agree the current title could be slightly misleading, but hopefully there is a middle ground. I don’t have a suggestion offhand, but if you do, HN moderators do tend to take user suggestions into account in these cases.
