This news item from a few weeks ago revealed that when users created a “public link” of their Claude chat history, that chat history ended up in Google’s search queries.

Aren’t these urls supposed to be more or less undiscoverable by virtue of the long string of random characters that they contain?

How did Google discover those urls?

Did these people publish the urls somewhere publically themselves?

Or did Google “fish” them out of their gmail inbox or something like that?
