Internet safety

I found the results of the 2001 survey on internet usage very shocking, I would have guessed the numbers to have been much higher. Before becoming a Teacher I worked for a short time as a web designer and from that experience I can't stress enough how true the following comment is "because those who prey on children circumvent
the safety features of the filtering software much as virus writers attempt to defeat
virus protection software."

The designers of a lot of pornographic site make their money by advertising and not the x-rated content, so they have lot of different way to trick children and adults into finding their sites.

One very simple way to trick search engines into displaying their site. Is to print lots of common search terms on their web site (Disney, Pop Groups, Movie titles, Actor/ess etc...) in the same colour as the background of their site. This way the search engines will find the site but won't be seen by the the viewer. (try searching for Disney and sex in google and you will get 3.7 million sites)

While the solution might seem to be use one of the filtering software. Filter programs work by looking for text which contains terms is has listed as inappropriate and blocks those sites. The web designers of these site has several tricks to get around this. The most common way is to not to use normal text on the site but instead create all the word and save them as an image.

you should also check out this site it tell people how to bypass filtering software. It's one of many sites online telling the determined person how to get around all the preventions measures that get put in place.
