Google algorithm inadvertently takes down ring of Chinese car thieves

Machines are becoming alarmingly intelligent, smart enough to root out crime.
A group of Google engineers tasked with looking out for online fraud and ad spam noticed something strange recently: photos of cars for sale in China kept getting flagged — not by the humans, but by a search engine algorithm.
Scammers were posting images of cars they didn’t own, breaking into them and selling them for money. So, how did Google detect the con?

It’s not an airtight system: more than a few valid accounts have had their orders delayed while the team checked them out.
