on The U$.$S$.$ Children's Internet Protection Act $($CIPA$)$ mandates that public schools and libraries employ mechanisms to block inappropriate matter on the grounds that it is deemed harmful to minors, Blocker Plus is an automated Internet content filter designed to help these institutions comply with CIPA's requirements. To accomplish this task, Blocker Plus was designed with a centrally controlled blacklist maintained by the software maker. In addition, Blocker Plus provided a user$-$friendly interface that made it a popular product for home use by parents. Due to the challenge of continually updating the blacklist, the makers of Blocker Plus have begun to explore machine learning techniques to automate the identification of inappropriate content. During the development of these changes, Blocker Plus combined input from both home and library users to aid in the classification of content. Pleased with their initial results, Blocker Plus deployed these technika in their production system. Furthermore, Blocker Plus continued to collect input from users to refine their learned mod During a recent review session ment team reviewed a number of recent complaints about content being blocked inappropriately. An increasing amountar content regarding gay and lesbian marriage, vaccination, climate change, and topics not covered by CIPA, had been added to the blacklist. Initial investigations into these incidents suggested that the were a number of activist groups that had exploited Blocker Plus's feedback mechanism to provide input that corrupted the classification model. Determining that there was no easy way to correct the model, Blocker Plus's leadership chose to disable accounts linked to the activist groups, while keeping the existing model intact in the hope that a correction could eventually be made. The legal and business risk, they determined, would be greater by switching to an outdated model that failed to block known bad content.
