Serious question though...

Do you have your pics automatically synced to backup/upload to Google Photos or Drive?

Also, have you gone into the advanced settings where they hide all the shit and unchecked 'anonymous' analysis type settings and other stuff they opt you into by default?

It's probably adsense using Google Image scan on some service your photos sync to and Google Ads you seeing on Facebook.

Still though, I know what you're saying but doubt anyone is manually looking at them...though they could if they want. But we already knew that what with the fact that they are actually part of the Gov/Corp Fascist NWO conglomerate.
