For those here who didn't know specifics, as far as I know the EU has announced in July 2025 guidelines, set to come into effect until 2026, that seem to basically be the same as the UK online safety act:

These guidelines say, among other things, check the last link: "Where the provider of the online platform has identified medium risks to minors on their platform as established in its risk review [...] and those risks cannot be mitigated by less restrictive measures. The Commission considers this will be the case where the risk is not high enough to require access restriction based on age verification but not low enough that it would be appropriate to not have any access restriction [...]" And "Self-declaration is not considered to be an appropriate age-assurance measure as further explained below."
If you don't want the Online Safety Act in the EU, call or e-mail your representative now. If you enter your country here, it shows a list: https://fightchatcontrol.eu/#delegates As far as I can tell, unless it's reversed this will be coming soon. The clock is ticking.
