Australian Prime Minister Julia Gillard has renewed her support for a controversial new web filter, saying the measure was driven by a  “moral question“. The proposed filter will block access to material such as rape, drug use, bestiality and child abuse. Internet giants Google, Yahoo and Microsoft have criticised the plans, saying they set a worrying precedent for further censorship. There are also fears that the restrictions could be applied to legitimate information on issues such as euthanasia, abortion and drug addiction, as well as media reporting on criminal activity.
