I worked in adtech. I built a simple ML system that detected signals of fraud on our network. When I reported my findings execs told me the group that was facilitating the fraud was our only profitable division. Soon after, our company went bankrupt. My final paycheck was months late.

Sounds exactly like my former employer ha.

IIRC our system wasn't even fancy ML - just finding known user IDs with identical timestamps over many simultaneous clicks / impressions on really diverse publishers.
