AI Incident Database · article · Aug 20, 2024 · UTC

Microsoft's Copilot is reported to have falsely accused veteran court reporter Martin Bernklau of committing serious crimes, including child abuse and fraud. The tool is described as having generated defamatory content that not only accused Bernklau of multiple crimes he covered as a journalist but also provided his personal contact details. Attempts by Microsoft to remove the false entries were only temporarily successful, as the defamatory information reportedly reappeared.
