Facebook has written to the Los Angeles Police Department (LAPD), demanding that it stop setting up fake profiles to conduct surveillance on users. From a report: This comes after the Guardian revealed that the US police department had been working with a tech firm, analysing user data to help solve crimes. Facebook expressly prohibits the creation and use of fake accounts. The intent, it said, was to “create a safe environment where people can trust and hold one another accountable”. “Not only do LAPD instructional documents use Facebook as an explicit example in advising officers to set up fake social media accounts, but documents also indicate that LAPD policies simply allow officers to create fake accounts for ‘online investigative activity’,” wrote Facebook’s vice president and deputy general counsel for civil rights Roy Austin in a letter outlining Facebook’s policies. “While the legitimacy of such policies may be up to the LAPD, officers must abide by Facebook’s policies when creating accounts on our services. The Police Department should cease all activities on Facebook that involve the use of fake accounts, impersonation of others, and collection of data for surveillance purposes.” Read more of this story at Slashdot.
