I feel like downvotes kinda make sense given that they said group has a lot of parents/children and siblings. I don't even know if this is bait or not.
Yours is the first mention I've found of children as members in that community, and its an NSFW-allowed community, so I have no idea where you got that notion.
That said, I would block any minor or minor-welcoming instance I became aware of on Lemmy. I'm not here to interact with that level of immaturity; I still regret not leaving facebook the moment they allowed teens(and grand-parents/boomers - yes it was an all-at-once change).
Not legal children, I meant children of other members of the community. Not overt pedophilia, just weird bordering incest that I understand people being averse to.
They say they aren't letting blood relatives have sex but I would still feel odd belonging to a relationship with my dad and sister where everyone is having sex with all of us.
