Ton-That sought to recruit other extremists, too. He wrote in a November 2016 email that he wanted to “totally hire” Emil Kirkegaard, a Danish eugenicist who had scraped OkCupid and published the data of nearly 70,000 users. Kirkegaard, who did not respond to questions, had infamously advocated to legalize child porn and lower the age of consent to 13 or the onset of puberty.

Ton-That called him a “total talent.” Emails show the CEO bounced facial recognition ideas off Kirkegaard, hoping to figure out how to identify gay people, or even predict criminality, from facial features.
