I really don't think there's much upside for a content creator to have a community which is welcoming to minors. If you're someone who's capable of acting inappropriately with minors in DMs like that Genshin VA, and I'll give some people the benefit of the doubt and say that they might not know they're capable of it until it happens, then you're baiting yourself for some serious trouble. Even if you are not one of those people, having a community welcome to both minors and adults means having a community which is welcoming to other adults who are one of those people. And even if you have both children and adults in a community and nothing untoward ever happens, you still have the chance that a minor can make a life-ruining accusation that something did. Some kids know they have this power over adults and like to throw it around since there's no consequences for them to do so. (Ever been in an argument on Twitter and then one of the participants just busts out with "um, I'm a minor, so stop replying to my tweets, you pedo?" That garbage makes me see red. If I ever get arrested for murdering a child it's gonna be after one of the little twerps tweets that at me.) So what's the upside? Is the slim chance of getting a valuable community member who happens to be an open minor worth all the potential for trouble that comes along with it? No. I really think the smart play is to just kick out any open minors in my community (such as it is). It's the safest choice for everyone.
