I think the most important thing a parent can do for a child is develop a strong bond of trust. Be consistent in what you say and do and be honest about any questions they ask. If you're going to make a rule, stick to it, but also show them at an early age that you think they can be trusted. If they trust you and you tell them that going to x site is bad, they will be much more likely to believe you and avoid the site. If they do go to x site and discover that it's bad, they'll tell you about it as long as you don't have a track record of punishing your kid for telling the truth, and you have the opportunity to talk it out and make sure your kid is okay. If your kid just doesn't want to listen, then maybe install a monitoring/blocking program. Also, especially do that when they are very young. You don't really need to do it above age 8 or so, as hopefully by then they will have developed a rhythm with the Internet that suits them.
