According to the newspaper NRC, Russian internet trolls tried to influence public debate in the Netherlands and Belgium using Twitter accounts that, according to Twitter, are linked to the "troll factory" Internet Research Agency in St. Petersburg, which is linked to the Russian government. The newspaper used two archives for its research, as Twitter already removed the involved accounts. One archive was sent to NRC by an anonymous source, the other can be found on the website of American news channel NBC. Together, the archives contain over 200,000 tweets by at least 3,841 IRA accounts.
