There are several moderated chat rooms that are safe for children and young teenagers, including Kidz World and Kids Online. These two examples are geared towards children and have safety features to protect them from online predators.
Good chat rooms for children are diligently moderated, have easily accessible ignore or block buttons, publish clear safety guidelines and provide a simple way for users to contact a moderator to report misconduct. It is also important for children to learn about Internet safety at home or at school. Above all else, parents should explicitly instruct their children not to give personal information to strangers on the Internet.
