The ban will encompass any news-media organization found to be “financially or editorially controlled by the state.” Cue the jokes about CNN and Fox News from their respective political detractors. The blog post announcing the ban states: To determine which outlets fall afoul of the new policy, Twitter’s compiled a list of state-sponsored media outlets based on information provided by “Reporters Without Borders Press Freedom Index, Freedom House, the Economist Intelligence Unit Democracy Index, the European Journalism Centre’s Media Landscapes Report, the Committee to Protect Journalists, and UNESCO’s framework to assess media development and independence.” Based on the text of the announcement, it appears as though the crackdown won’t just be limited to those outlets directly linked to government oversight but also those with compromised journalists: Politically-sponsored misinformation campaigns are all the rage on social media (see our explainer on Cambridge Analytica’s successful efforts to influence the 2016 US presidential election here). But increasing scrutiny from lawmakers and push-back from users has forced companies such as Facebook and Twitter to take continuing steps to address the problem. This policy will not apply to entities that are solely dedicated to entertainment, sports, and travel content. However, if the content is mixed with news, it will be prohibited. Twitter will be contacting companies and persons affected by the ban and affording them thirty days to disassociate themselves from the company’s advertising products, at the end of which they’ll face “stringent enforcement.” Affected accounts that comply with the request to off-board from Twitter’s advertising products will remain free to continue using the social media platform, but they won’t be able to advertise. The company says this move should prevent these state-run campaigns from winding up in the feeds of users who don’t follow the outlets creating them.
