But it’s Google, so they know your browsing history and have you in a “bucket” for what their metrics think will drive engagement from you. (Or they don’t know enough about you and just think boobs will get you intersted, because sex sells.)

Meh. We’re all human. If Google thinks you like thirst traps, whatevs. Pretty ladies are pretty ladies.
But if you don’t want to see it, you can probably use feedback tools to change what they show you.
