This is my goto:

First, at scale, if an engineer can think it, statistically speaking there is an engineer who will do it.

So let's pick a theoretical: Imagine you have all these photos of people with their faces - at the club, hugging at the pub etc. Then you can track who has a criminal record, due to what they post, key words, etc. And then you can track who statistically speaking, has a high chance of having a criminal record (but may not have). Then you can track these individuals moving around in various social circles. And then you look at peoples group photos, and raise a flag when there is cross-over between the circles. This is vastly interesting of course, but... who said it was cool to examine me and the people I meet to make that judgement? Even if FaceBook are not doing it now, who said it was cool to amass all this data so they CAN make this judgement, at anytime in the future.

This behaviour in a person is called being "a bit judgey". When facebook do it, it's "a bit judgey"...with parallelized computing and machine learning.

I'm not a criminal. I'm a totally chill guy. It literally wouldn't make me worried for myself if Facebook did this. But, I just find the whole role they can play...annoying.
