Several countries now describe how adult sites should check a visitor's age. Below we summarise what each regulator's own texts say, link to them, and show what No451 checks. Whether a rule applies to your site depends on your service and your visitors. A lawyer can confirm whether that's you.
JMStV § 4 Abs. 2 says pornographic content may be offered online only if the provider ensures, through a closed user group, that only adults have access. The KJM assesses age-verification systems.

Our regulations map lists the countries we cover with links to each law and regulator, including Germany (JMStV), the UK (Online Safety Act), France (loi SREN, Arcom) and Italy (AGCOM). Each country page says when we last checked it.
Each law defines its own scope. The UK Act (s. 80(4)) looks at whether a service has a significant number of UK users or targets UK users. JMStV § 2 covers providers outside Germany whose service is intended for use in Germany, with limits for other EU countries. A lawyer can confirm whether that's you.
We load your site like a first-time visitor from the countries you pick and report what we saw: which kind of age check appears, what is visible before it, and whether media files open without it.
No. We describe what we observed on a given date. Only the regulator, and your lawyer, can assess your site against the law.
Not legal advice. This page summarises and links to primary sources; it does not tell you what the law requires of your specific site.
