Much of the Internet Censorship debate was aroused with a 1995 cover story from Time magazine. It is largely based on a research paper by Marty Rimm and a research team of students at Carnegie-Mellon University in Pittsburgh. There are many arguments both for and against the censorship of the Internet. Many politicians claim that they are fighting for the children and their parents.
Many teachers are afraid that being online at school puts kids at risk there.
There are many others that say that filtering out all of the bad also filters out a lot of good. If the filtering products and services used to censor the Internet filtered out everything, or even most, of what was bad, there would be no controversy. However, many filters use techniques that filter out information on things like breast cancer. Filtering software programs can work in many ways. They can guard against certain keywords or use site blocking.
