The Rulez here (see links in the upper right corner) strictly forbid posting of photos of minors. If a moderator has good reason to believe that a model is under-age, the moderator is obliged to delete any posts involving that model. Note that the entire post will be deleted, since only Ninja can edit posts.
In another thread, somebody said that PC had earned the right to post anything he wanted. We certainly should be grateful to PC for his prolific long-hair posts, but that does not exempt him from the Rulez. We will probably cut him slack on things like jokes and cartoons, but if he posts something that is way off-topic and has no redeeming long-hair material, that post is likely to get deleted.
We don't require anybody's posts to be 100% on topic, whether it's PC or Azazel or anybody else. If you've got several good long hair links and want to throw in a link to a short-haired model that you really like, feel free to do so, but be courteous and say in your post when a link is not long-hair related and don't hot-link to photos of models who don't have long hair.
