Tell your child that a meeting with an online person should never be arranged. No gifts from friends online should ever be accepted, just as candy should not be taken from a stranger in the mall. No pictures of any family members should be posted, or emailed to strangers. Explain that any offensive language or inappropriate discussions should be reported immediately to the host of the room, or the online service. Email is a wonderful tool, that helps family and friends keep in touch.
Email can also have pictures or links to sites in it that are inappropriate for younger viewers.
Adult sites that contain pornography send out large amounts of spam every day. This procedure is akin to telemarketers cold calling random phone numbers when trying to sell their wares. The best way to deal with this type of spam is to check the email address, and send it to your online service member support area. They will then ban further emails to all members. Your child changes the screen, turns off the computer or shuts off browser when an adult enters the room.
