Google Researchers’ Attack Prompts ChatGPT to Reveal Its Training Data
(www.404media.co)
This is a most excellent place for technology news and articles.
We don't, but from what I've seen in the past, those sort of forums either require registration or payment to access the data, and/or some special means to download it (eg: bittorrent link, often hidden behind a URL forwarders + captchas so that the uploader can earn some bucks). A simple web crawler wouldn't be able to access such data.
