I should first mention: we don't allow kids under 13 on the site, because dealing with COPPA is ridiculous.
That having been said, there's no difference between "13" and "17" -- anybody under the age of 18 can't see material marked 18+. LJ has two levels of "adult content" (14+ and 18+) but we only have 18+ (blocks access to anyone not 18 or older) or "NSFW" ("this post is probably not work safe, are you sure you want to see it?" but not tied to an age restriction.)
Anyone can change their birthday with the site at any time, but the 18+ restriction uses the DOB given at registration, not the one given on the profile edit page. So a kid who switched their DOB on their profile after class was over would get points for trying, but no smut. *g*
