Facebook has taken down a network of hundreds of fake accounts and pages targeting people in Ukraine and linked to individuals previously sanctioned by the United States for efforts to interfere in U.S. elections, the company said Thursday.Facebook said the network managed a long-running deceptive campaign across multiple social media platforms and other websites, posing as independent news outlets and promoting favorable content about Ukrainian politicians, including activity that was likely for hire. The company said it started its probe after a tip from the FBI.Facebook attributed the activity to individuals and entities sanctioned by the U.S. Treasury Department, including politician Andriy Derkach, a pro-Russian lawmaker who was blacklisted by the U.S. government in September over accusations he tried to interfere in the 2020 U.S. election won by President Joe Biden. Facebook said it removed Derkach’s accounts in October 2020.Derkach told Reuters he would comment on Facebook’s investigation on Friday. Facebook also attributed the network to political consultants associated with Ukrainian politicians Oleh Kulinich and Volodymyr Groysman, Ukraine’s former prime minister. Kulinich did not immediately respond to a request for comment. Groysman could not immediately be reached for comment.Facebook said that as well as promoting these politicians, the network also pushed positive material about actors across the political spectrum, likely as a paid service. It said the activity it investigated began around 2015, was solely focused on Ukraine, and posted anti-Russia content.”You can really think of these operators as would-be influence mercenaries, renting out inauthentic online support in Ukrainian political circles,” Ben Nimmo, Facebook’s global influence operations threat intelligence lead, said on a call with reporters.Facebook’s investigation team said Ukraine, which has been among the top sources of “coordinated inauthentic behavior” that it removes from the site, is home to an increasing number of influence operations selling services.Facebook said it removed 363 pages, which were followed by about 2.37 million accounts, and 477 accounts from this network for violating its rules. The network also spent about $496,000 in Facebook and Instagram ads, Facebook said.

Twitter wants to curb what the company calls “potentially harmful or offensive” tweets.  The social media company announced Wednesday it has released a feature that can detect a mean tweet and prompt a user to be sure they really want to send it. “People come to Twitter to talk about what’s happening, and sometimes conversations about things we care about can get intense, and people say things in the moment they might regret later,” the company said in a blog post. “That’s why in 2020, we tested prompts that encouraged people to pause and reconsider a potentially harmful or offensive reply before they hit send.” The prompt says: “Want to review this before tweeting?” Users can then decide whether to send, edit or delete the tweet. Twitter did not specify what would be considered “potentially harmful or offensive.” The company currently has a similar feature that asks users if they went to read an article before retweeting a link to the article. Twitter’s new mean tweet detector has been tested for the past year and will be rolled out soon to English-language Twitter. The company said that while testing, 34% of users, when prompted, either edited the offensive tweet or did not send it at all. Last week, Twitter stock plunged 10% on lower-than-expected user growth.
