I'm thinking of something like YouTube Kids - I don't know a whole lot about it but as far as I know, kids will ONLY see videos that are explicitly FOR KIDS. I would recommend the same thing for VRChat. The normal user's experience remains untouched. Literal children would ideally either have their parents set it up for them, or otherwise they would identify as a child (again - very important - these are dumb kids with innocence who still identify as a kid) and thus would opt-in to the kid version of the game, thinking that they are tailoring the experience for themselves (presenting it like they'll make friends of similar age and giving it a fun identity). 

I think the system would work. The target audience would opt in. This is not an 18+ button - this is a kids button. It not censoring or removing content, it is tailoring the experience for kids.
