From a long time ago (~2009) but this comment instantly reminded me of the gem which was Plenty Of Fish

"POF has one single employee: the founder and CEO Markus Frind. Makes up to $10 million a year on Google ads working only two hours a day. 30+ Million Hits a Day"

Thank you for sharing! Only issue with the article I see is that "CPM" is already "cost per mille (thousand)". So any lines such as "$15 per CPM" make me hesitate.
