Probably the best step you can take as a parent is to communicate with your kids about what is appropriate Web behavior. If you keep the lines of communication open with your children, they are much more likely to understand why you want them to stay out of certain sites on the computer and be willing to comply with your wishes.
Another step to take is to add filtering software to your home computer that your children will be using. After it is on your hard drive, if someone tries to type a word like "sex" into a search engine, the filtering software works so that no pornographic images or sites come up on the screen. However, there are some flaws with this system. If you have an older child that uses the Internet for research for school assignments, the filter will sometimes do too good a job of keeping information at bay. If you are researching first ladies, for example, and you type in "Onassis" with filtering software turned on, you will get nothing back from the search because the name Onassis contains the word "ass," which is a filtered-out word on the software. Filters can also be used to restrict e-mail access and can be set to lock children off the Internet at certain times that you cannot be immediately available to supervise their computer use.
Pornography is a form of freedom of speech, according to case results from the US Supreme Court, and therefore it is not kept off the Internet or out of stores. There is not a law that would limit porn so that children would not have access to it, because of the worldwide nature of the Internet. Just because a law might be passed to limit porn to minors, that might not be the case in another country, and the Internet offers access to all. Filtering software is the Supreme Court's answer to this issue, and it is up to parents to install it and activate it.
Some adult entertainment sites that you might enjoy, such as FTV Girls or Milfhunter, might not be where you would like your children to go online, and so filter software can be set to restrict access to specific sites you wish. There are also a range of filters, so you can set it for maximum to minimum filtration. You could choose to severely limit Internet site access for very young children, while opening it up a bit more for older teens. Most authorities agree that the best filter is the parent and his or her talking with their kids about harmful sites, and providing supervision so that they do not get into trouble online.
