In an open letter to Prime Minister Kevin Rudd, Reporters Without Borders states that the web filter is not the solution to combating child sex abuse, and the plan entails risks to freedom of expression. The censorship of websites by ACMA, rather than a Judge, is in contravention of laws. The criteria for censoring "inappropriate" websites is too vague, and it would be a dangerous censorship option to target "Refused classification" sites, many of which are unrelated to sexual abuse. Subjects such as abortion, anorexia, aborigines and legislation on the sale of marijuana would all risk being filtered, as would media reports on these subjects.
