Geofeedia isn't the only social media surveillance company giving data to police

Twitter shut off commercial access to Geofeedia on Tuesday after the ACLU revealed that Twitter, Facebook and Instagram data was being marketed by Geofeedia to police as a way to monitor activists and protests. SEE ALSO: Social media companies suspend Geofeedia's access after reported police tracking Facebook and Instagram had also recently severed much of Geofeedia's access to their networks for the same reason. Based on information in the @ACLU's report, we are immediately suspending @Geofeedia's commercial access to Twitter data. But social media surveillance companies are proliferating, and Geofeedia is not the only one that has seen an opportunity in marketing their services to police departments by telling police they could track hashtags associated with Black Lives Matter protests. Media Sonar, whose website says it has "proven" to be a "powerful tool for assessing threats," was found to market their services to the Fresno Police Department, according to results of an investigation by the ACLU published in December, 2015.
