Is it illegal to build a gender health website?

This involves the double standards of law and ethics. It is right to say that you are legal; Say you're illegal. See from what angle to look at you. Objectively speaking, building this website is nothing, because your content and starting point are to guide health. But different netizens may see different things from it, and the effect of being "educated" (also an education) is different. Just like a gangster film, its positive significance is to show righteousness and combat darkness, but many criminals feel the criminal methods from the gangster film. For another example, in art photography, nude photography can show the level and strength, but you can imagine how many people click on those pictures when you put them on the internet to enjoy the art. Therefore, it doesn't matter whether it is illegal or not. I'm just afraid that if you do it with your heart, you won't get good results, which may be counterproductive. Suggest, do something else, don't dive into this water!
