Software tools that scan for porn can deal with locating any text files and analyzing their contents. This involves comparing keyphrases against an array of known keyphrases compiled previously. These are normally adult oriented phrases suggesting inappropriate behaviour and other material; unacceptable topic matter or racism, articles about violence, text inciting hate or any such unacceptable items; improper system use; these can all be picked up and then given as the results in the output results. Suspicious items found can be assigned if necessary for further testing by the operator, so that a decision is made that determines the handling of unwanted items in the preferred manner.
