Are there spelled out rules for how to do age verification or what's necessary to have a user agree to. It just seems like every site except HN asks your permission for cookies. I have a site that is 21+ themed, but nothing for sale and not adultxxx. Just pictures of (legal for me) plants. I've tried to google it and I have found some answers, but I am reluctant to trust the AI answers I found. Any guidance is appreciated.
