Via The Domains

Sexually explicit content is prohibited (X18+, and Refused Classification content).

* R18+ content (non-sexually-explicit, but restricted) must be hidden behind a verification service that checks for ages 18 and up.
* So-called “Mature audience” (MA15+) content must also be hidden behind a verification service that checks for ages 15 and up.
* The Act will use “take down,” “service cessation” and “link deletion” notices to force publishers to remove content or access to content that is the subject of a complaint.

Users will have to supply their full name, and either a credit card or digital signature.

The new rules also apply to live chatrooms, which is a whole different problem.
