There is no such thing. Laws only ever apply on a country-specific basis. This may certainly be an important aspect in relation to operators of websites that fall under these laws. However, private individuals who operate a private website are exempt from this.
Of course, it cannot be denied that most forums are operated by legal entities / “clubs” / “societies” / companies that fall under the laws. Nevertheless, I would still like to be able to manage without third-party providers.
That is the only way to practise data protection & garantee privacy. When profiling/tracking is completely prevented by 3rd parties. When users who visit a website can be sure that their digital movement profile remains private. And the website operator can still check the security and legitimacy of its community.
