A look into the system that USA immigration uses to trawl everyone's social media feeds

404 Media reports that the USA's Immigration and Customs Enforcement (ICE) has "used a system called Giant Oak Search Technology (GOST) to help the agency scrutinize social media posts, determine if they are 'derogatory' to the U.S., and then use that information as part of immigration enforcement". Screenshots in the article show how GOST allows ICE to "search the system with identifiers such as name, address, email address, and country of citizenship" and display a "ranking" from 0-100 on how troublesome that user is based on their social media activity. I think we all kinda knew that the USA's (and probably many other countries) border police did this kinda thing, but to see it in action is a bit disturbing.
