Things to consider:
1. Filters may not work very well.
Sites with sexual content are often on the move, and even the
most industrious and conscientious filters have trouble keeping
up with smut peddlers. If you're really looking for dirty pictures,
you can probably find them, filter or no.
2. Filters may work too well.
If the screens are too rigid, they may block students from learning
about perfectly normal, natural and non-controversial aspects
of human sexuality and scientific information.
They may block students from totally innocent sites needed for
their research. Real examples:
3. Filters may increase attention to that which is forbidden
Adolescents are naturally drawn to the Web for music sites, clothing
and cars -- not pornography. The impact of a filtering message
might create just the opposite effect.
4. Filters may create a false sense of security.
The decision of whether or not to use
a filter in your home, and which one to choose, is a personal
decision. Many filters are on the market and are capable of vastly
different things, from blocking chat and transmission of information
to monitoring your hard drive and keeping history lists. The filter
also has to be easy to install and update, and parents need to
know about all of its functions so that they can take full advantage
of what they have bought.
