You have to be constantly on your guard when communicating in cyberspace. Be careful about whom you add to your friends list and block anyone from sending you messages. Report suspicious behavior to the moderators who enforce the rules and terms. Use password protection whenever you can, like for comments on social networking sites or blogs. Use a Safer Social Network to reduce the dangers of weirdo strangers and weirdos. Check with your friends before posting anything about them online to protect your own safety. Use the COPPA (COPPA) to see if a child’s social networking site is a reliable and trustworthy company.”]
