How did Facebook react to the much larger data harvesting of the Obama campaign? The New York Times reported it out, in a feature hailing Obama’s digital masterminds:
The campaign’s exhaustive use of Facebook triggered the site’s internal safeguards. “It was more like we blew through an alarm that their engineers hadn’t planned for or knew about,” said [Will] St. Clair, who had been working at a small firm in Chicago and joined the campaign at the suggestion of a friend. “They’d sigh and say, ‘You can do this as long as you stop doing it on Nov. 7.’ "
In other words, Silicon Valley is just making up the rules as they go along. Some large-scale data harvesting and social manipulation is okay until the election. Some of it becomes not okay in retrospect. They sigh and say okay so long as Obama wins. When Clinton loses, they effectively call a code red.
