If it wasn’t obvious by now, Twitter has a major bot problem.

Last month, executives from the social network told the US Senate’s intelligence committee they had found evidence that Russia was behind some fake and automated accounts active during the 2016 presidential election. Studies have found that around 20% of election-related Twitter activity came from suspect bot accounts. Other highlights from the past year include the bots deployed to slander French presidential candidate Emmanuel Macron and to exacerbate the standoff between Qatar and its neighbors in the Gulf.
