Do digital platforms function as stealth media, a system that enables the deliberate operations of undisclosed political campaigns’ imperceptible targeting and furtive messaging? This talk presents empirical research on covert digital political campaigns sponsored by unidentifiable, untraceable groups. By utilizing a user-based, real-time ad tracking tool and “reverse engineering” techniques, independent from tech platforms, Kim’s research reveals the prevalence of foreign and domestic undisclosed campaigns and uncovers targeting, messaging and organizational strategies of such undisclosed campaigns. The talk offers insight relevant for regulatory policies and discusses the normative implications for the functioning of democracy.
