Is it possible to make sections on the site for different ages 0+ and 18+?

Question

Search Engine Optimization

Good evening!
The site with entertainment content has 4 sections with an age limit of 0+. If I add a fifth section of 18+ erotic content, will it affect the site's ranking in search engines? Or with the presence of such a section, the search engines will brand the entire site as an adult? Are there any meta tags to indicate age restrictions on different pages?
Well, in fact, is it possible to put ads from Yandex / Google in sections 0+, and other ads in section 18+, or is it immediately banned?

Answer 1

Have you yourself tried to look for this information in the PS in the requirements for the quality of content?
Respect the required quality and do not break the law.
Basically, everything.
