I believe many AI tools like Gemini generate publicly accessible URLs when we click "Share" on any chat conversation -- and expect users to then own the lifecycle of that link
Depending on how the link gets handled -- by the browser, device OS, any hooks/plugins/extensions, aggressive telemetry, social media url previews, preload/prefetch, wrapping and url shortening, etc as it reaches the intended user -- there are countless ways in which the URL can be indexed and scraped
There was a issue not long ago when Claude artifacts were indexed en-masse by Google and other search engines
This is shockingly lax approach to data security and privacy by design
