If someone without special clearance uploads explicit loli, it can simply be deleted. However, sometimes people with automatic approval mistakenly upload explicit loli. In this case, the appropriate tags and ratings are put in place so that no one besides Mods will be able to view it.

I was told that we don't delete all of the existing explicit loli content just in case it's ever decided by Admins to start allowing it. Since most people still prefer us not to have that content, those images stay hidden.
