Users interacting with unreliable content are more likely to be toxic across political divides.
Abstract
In this work, we examine the influence of unreliable information on political incivility and toxicity on the social media platform Reddit.

Using a regression model, we show that these results hold after accounting for partisanship and baseline toxicity rates within individual subreddits. Utilizing a zero-inflated negative binomial regression, we further show that as the toxicity of subreddits increases, users are more likely to comment on posts from known unreliable websites. Finally, modeling user interactions with an exponential random graph model, we show that when reacting to a Reddit submission that links to a website known for…
