ProPublica

In August, ProPublica filed public-records requests with every governor and 22 federal agencies, asking for lists of everyone blocked on their official Facebook and Twitter accounts. The responses we’ve received so far show that governors and agencies across the country are blocking at least 1,298 accounts. More than half of those — 652 accounts — are blocked by Gov Matt Bevin (R-KY). Four other Republican governors and four Democrats, as well as five federal agencies, block hundreds of others, according to their responses to our requests.

Russian disinformation isn’t the only deceptive political advertising on Facebook. The pitch designed to lure President Donald Trump’s critics is one of more than a dozen politically themed advertisements masking consumer rip-offs that ProPublica has identified since launching an effort in September to monitor paid political messages on the world’s largest social network.

The Department of Immigration & Customs Enforcement is taking new steps in its plans for monitoring the social media accounts of applicants and holders of U.S. visas. At a tech industry conference in Arlington (VA), ICE officials explained to software providers what they are seeking: algorithms that would assess potential threats posed by visa holders in the United States and conduct ongoing social media surveillance of those deemed high risk. The comments provide the first clear blueprint for ICE’s proposed augmentation of its visa-vetting program.

In February, Facebook said it would step up enforcement of its prohibition against discrimination in advertising for housing, employment or credit. But our tests showed a significant lapse in the company’s monitoring of the rental market. Last week, ProPublica bought dozens of rental housing ads on Facebook, but asked that they not be shown to certain categories of users, such as African Americans, mothers of high school kids, people interested in wheelchair ramps, Jews, expats from Argentina and Spanish speakers.
