Age-Appropriate Social Websites
Online companies cannot legally collect information from kids younger than 13. It's not really about maintaining safety, but it's probably true that many tweens have not yet developed the maturity or consistent level of responsibility necessary to handle the kind of online communications that happen on social sites. It's very hard for kids to understand the consequences of their actions or to imagine that there are actual other people on the other side of that screen they are typing into—so the younger kids are, the more likely they are to be impulsive, post things that could get them into trouble or encounter cyberbullying.
Talk to your kid about behaving responsibly and respectfully online—and that means following sites' terms of service which include age restrictions.
