Would not recommend for kids
If you're looking for answers, this might not be the best place for it for the following reasons, especially for kids:
1. The site is overrun with users who give unhelpful, insulting, or inappropriate answers.
2. The site has a system that allows users to report any question or answer they deem inappropriate or against the site's rules. Unfortunately, this system is constantly abused by users who report innocent questions and answers to upset other users. As a result, many good, valid questions that don't break the rules end up getting deleted every day, which frustrates other users all the time.
3. Although swearing is censored, some users have found ways to bypass this.
4. Some questions and answers contain subject matter that you would not want your kid to read or know about.
The site can be helpful sometimes, but I really wouldn't let your kid go near this place if I were you.
