The other day I saw the retraction of a leak of customer data, on the grounds that the claimed data was very obviously from an LLM, which outsiders could trust wasn't just the company saying so because of things like "the email addresses don't match the people's names" and "the zip codes don't correspond to the states they're supposedly in".

Unfortunately, I can't remember the name of the place that denied the leak, which makes it hard to search for amongst the torrent of attacks that I find in search results.
