Facebook has sent a letter to academics at New York University demanding that they stop collecting data about the political ads that Facebook runs, according to a report this evening[1] by The Wall Street Journal's Jeff Horwitz, citing written remarks by the social network. 

The objection by Facebook pertains to an NYU project called the Ad Observatory, which uses thousands of volunteers who surf the social Web site with a special browser extension to gather data on which ads are shown to what people.

In a letter sent October 16th to the NYU researchers, a Facebook privacy policy official, Allison Hendrix, stated in that "Scraping tools, no matter how well-intentioned, are not a permissible means of collecting information from us," writes Horwitz. The data collection is a violation of Facebook rules that prohibit bulk data collection from its site, Facebook says.

The letter demands data be deleted and warns that persisting could result in "additional enforcement action."

The Ad Observatory began its works last month, Horwitz reports.

Horwitz cites a statement to the Journal from Senator Amy Klobouchar, Democrat of Minnesota, criticizing Facebook for its pressure on NYU. 

"It's unacceptable that in the middle of an election, Facebook is making it harder for Americans to get information about online political ads," Klobouchar told the Journal.

The warning to the NYU scholars comes amidst a rapid series of developments by Facebook and against the company in the past month or so. Facebook on October 7th said[2] it will suspend U.S. political advertisements in the U.S. after the polls close on November 3rd for the U.S. presidential election.  That follows a prior decision in September[3] by the site to refuse new political ads in the week leading up to the election.
