SAN FRANCISCO, June 22 (Reuters) - Facebook said it would not disclose information about political campaign advertising or related data such as how many users click on ads and if advertising messages are consistent across demographics, despite arguments from political scientists who want the data for research.
Details such as the frequency of ads, how much money was spent on them, where they were seen, what the messages were and how many people were reached would remain confidential under the company's corporate policy, which is the same for political advertising as for commercial customers.
"Advertisers consider their ad creatives and their ad targeting strategy to be competitively sensitive and confidential," Rob Sherman, Facebook's deputy chief privacy officer, said in an interview on Wednesday, when asked about political ads.
"In many cases, they'll ask us, as a condition of running ads on Facebook, not to disclose those details about how they're running campaigns on our service," he said. "From our perspective, it's confidential information of these advertisers."
Sherman said it would not make an exception for political advertising. "We try to have consistent policies across the board, so that we're imposing similar requirements on everybody."
Academics who study political campaigns worldwide said this kind of information fosters accountability by analyzing how candidates compete for votes and whether election systems live up to expectations of fairness. Transparency can also deter fraudulent ads, they said.
"We don't have the capacity right now to track it, and nobody does, as far as we can tell," said Bowdoin College professor Michael Franz, a co-director of the Wesleyan Media Project, which catalogs political ads on traditional television but has no means of doing so on Facebook.
Television has been the backbone of political advertising for decades, and local U.S. broadcasters are required to disclose a wealth of details about the cost and schedules of ads. The ads can be seen by anyone with a television provided they are aired in their markets.
Online advertising, though, often targets narrow, more carefully constructed audiences, so for example an ad could be directed only to Democrats under 25 years of age.
Thousands of variations of online ads can be directed at select groups and the targeting can be extreme. Academics argue this is where the process can become very opaque.
"Candidates can speak out of both sides of their mouths," said Daniel Kreiss, a communications professor at the University of North Carolina at Chapel Hill. "Having some kind of digital repository of ads that are purchased during a particular cycle and linked to a particular source is a good, democratic thing for the public."
