 Social media continue to drive a range of new philosophical investigations in the domains of  social epistemology  and ethics, including ‘vice epistemology’ (Kidd, Battaly, Cassam 2020). Such investigations raise urgent questions about the relationship between online disinformation/misinformation, individual moral and epistemic responsibility, and the responsibility of social media platforms themselves. On this point, Regina Rini (2017) has argued that the problem of online disinformation/misinformation is not properly conceived in terms of individual epistemic vice, but rather must be seen as a “tragedy of the epistemic commons” that will require institutional and structural solutions.
