Review of tech disinformation code promised after Mayfair 101 scandal Save Share Big Techâs voluntary disinformation code will be âcarefully reviewedâ come June, after the Mayfair 101 scandal raised serious concerns about the role Googleâs advertising technology plays in misleading the public, according to the Morrison government. The voluntary Code of Practice on Disinformation and Misinformation, which is managed by the Australian Communications and Media Authority, would also be reviewed, a government spokesperson said, in light of testimony given by Facebook, Google parent Alphabet and Twitter executives in the US last month, when Facebook called for reforms of how tech companies are held liable for misinformation and other harmful content on their platforms.
