Never enter an area that charges for services without receiving explicit parental permission. Remember that people online may not be who they seem to be. Follow these rules even when at school or at a friend's house. Children have access to the Internet in many places, but they should know that the same rules apply no matter where they are. Many parents have found that blocking software is an effective way to protect their children from harmful or inappropriate material on the Internet.
Different products offer various levels of parental input or control.
Even with blocking software, it is possible that your child might come across something you feel is inappropriate. Talk to your children about issues that concern you such as exploitation, pornography, hate literature, or excessive violence so that they know how to respond when they encounter such things both online and in the real world. However, remember that the best tools children have for screening material found online are the values you teach them.
