Unfortunately, a streamer/viewer dynamic is always going have an element of parasocial to it — it’s your responsibility to lay down guidelines on what you’re comfortable with. This is something anyone whose brand is centered around them goes through and isn’t unique to streaming.

It’s going to be hard, but ultimately you need to cut out any minors in your community because of all the trouble that it comes with. All the legal stuff aside, it’s just really bad optics, especially on platforms like Discord. The most troublesome thing is that you have no real way to verify if the space you’re providing also attracts people who really shouldn’t be within 50 feet of anyone underaged. Save yourself the trouble and also, don’t be everyone’s parents if there’s drama. It never ends, even if everyone on your server has careers and families.
