Where content is deemed to be prohibited, the ACMA is empowered to issue local sites with a takedown notice under which the content must be removed; failure to do so can result in fines of up to $11,000 per day. If the site is hosted outside Australia, the content in question is added to a blocklist of banned URLs. This list of banned Web pages is then added to filtering software (encrypted), which must be offered to all consumers by their Internet service providers. In March 2009, this blocklist was leaked online.
