workplace gossip and compensation, and negative opinions held of # companies. Over many years, as they change jobs or change their views, it is # important that they can delete or anonymize their previously-written answers. # # We opt out of the wayback machine because inclusion would allow people to # discover the identity of authors who had written sensitive answers publicly and # later had made them anonymous, and because it would prevent authors from being # able to remove their content from the internet if they change their mind about # publishing it. As far as we can tell, there is no way for sites to selectively # programmatically remove content from the archive and so this is the only way # for us to protect writers. If they open up an API where we can remove content # from the archive when authors remove it from Quora, but leave the rest of the # content archived, we would be happy to opt back in. See the page here: # # https://archive.org/about/exclude.php # # Meanwhile, if you are looking for an older version of any content on Quora, we # have full edit history tracked and accessible in product (with the exception of # content that has been removed by the author).
