Twitter Inc this month made a significant revision to its public database of more than 3,000 accounts that it has linked to Russia’s Internet Research Agency, fundamentally altering the record about the group’s trolling efforts in the US in the year following the contentious 2016 presidential election.
Twitter’s changes invalidate central portions of a Bloomberg News article published last August that had analysed the Russian troll farm’s activity in 2017, according to researchers at Clemson University who have compiled and published a database of the IRA’s Twitter activity.
