Has Google made this information public? Or are they just indexing it?
Societies usually ban that difference.
I know a few European cultures, most notably the Germans, make a big deal about this difference, but I'm not aware of other cultures where distinguishing between public-but-obscure and public-and-indexed is a thing.
In my opinion it's a terrible distinction to make, as it gives users false comfort about what's actually unavailable to the public.
The difference between "public and indexed" and "public but obscure" is huge.
It’s also the same difference as "taking a photo of outside" vs. "permanent video surveillance of everywhere".
