Actually illusions, it needs to be more specific still. It ought to say: Due to legal liability surrounding Children and Child pornography in the US we will not allow any nude pictures of anyone under the age of 18 in The MarketPlace. The word 'children' means different things in different places: here in the UK, it means under 16. And the bit about "advertised as teens" needs to be sorted out too. 'Teens' means 'between thirteen and nineteen inclusive'. If eighteen- and nineteen- year olds aren't children, then they shouldn't be included. Considering the amount of hassle this subject has caused over the last couple of years, I'd have thought someone would have the sense to get rid of the sloppy language and remove any room for doubt. Once it's specific, it's easier to enforce.
