ArchiveOfOurOwn (AKA AO3, run by the Organization for Transformative Works (OTW)) has been down for a few days due to a security incident. In the wake of that security incident, a site called AO3.life has cropped up. At some point, they scraped what appears to be most (if not all ... I've got no way to check that myself) of the fics on AO3 including ones that were only available to logged-in users.
In addition to providing these fics (some of which were specifically not intended for broader consumption) on their site, they're trying to get readers to pay for audio editions of the stories.
They have some dodgy and technically impossible steps if you are an AO3 author and want to take your fics down.
OTW is aware and is taking legal action but they warn that the legal system is slow. They advise that you do not attempt to use AO3.life's requested method since it may expose you to additional dangers regarding your private information.
