In this study, we interviewed 22 prominent hacktivists to learn their take on the increased proliferation of misinformation on social media. We found that none of them welcomes the nefarious appropriation of trolling and memes for the purpose of political (counter)argumentation and dissemination of propaganda. True to the original hacker ethos, misinformation is seen as a threat to the democratic vision of the Internet, and as such, it must be confronted on the face with tried hacktivists' methods like deplatforming the "misinformers" and doxing or leaking data about their funding and recruitment. The majority of the hacktivists also recommended interventions for raising misinformation literacy in addition to targeted hacking campaigns. We discuss the implications of these findings relative to the emergent recasting of hacktivism in defense of a constructive and factual social media discourse.
