Down the bot hole: actionable insights from a 1-year analysis of bots activity on Twitter

arXiv:2010.15820

Abstract

Nowadays, social media represent persuasive tools that have been progressively weaponized to affect people's beliefs, spread manipulative narratives, and sow conflicts along divergent factions. Software-controlled accounts (i.e., bots) are one of the main actors associated with manipulation campaigns, especially in the political context. Uncovering the strategies behind bots' activities is of paramount importance to detect and curb such campaigns. In this paper, we present a long term (one year) analysis of bots activity on Twitter in the run-up to the 2018 U.S. Midterm Elections. We identify different classes of accounts based on their nature (bot vs. human) and engagement within the online discussion and we observe that hyperactive bots played a pivotal role in the dissemination of conspiratorial narratives, while dominating the political debate since the year before the election. Our analysis, on the horizon of the upcoming U.S. 2020 Presidential Election, reveals both alarming findings of humans' susceptibility to bots and actionable insights that can contribute to curbing coordinated campaigns.
