Masked groups refer to collections of individuals who conceal their identities, often using masks or other disguises. These groups can form for various reasons, including social, political, or artistic expression. The anonymity provided by masks can encourage participants to express themselves more freely and engage in activities they might not otherwise pursue. In some contexts, masked groups may be associated with protests or movements, where participants aim to protect their identities while advocating for a cause. Examples include Anonymous, a hacktivist group known for its online activism, and various cultural events like Carnival, where masks are worn for celebration and anonymity.
