<meta name="RATING" content="RTA-5042-1996-1400-1577-RTA" />

I wonder why the rating code is so complex. Pornhub.com has this code enabled, but it also uses a simpler <meta name="rating" content="adult">. 4chan also uses the latter.

I can't find any information on https://rtalabel.org/ to explain why that specific string, but I appreciate that the string being unique made it easy to find the official website, compared to something generic like "adult".

Maybe because it leads people to cease providing non-rated contents, contrary to the intent of regulations.

I think it should be fairly simple client code to look for either of them.

probably for uniqueness. This code is set by a very specific standard while adult could mean almost anything.
