# Anonymous **Anonymous** is a decentralized international hacktivist collective that emerged around 2003 out of imageboard culture (notably 4chan) and became one of the defining leaderless digital movements of the early 2010s. It has no membership, no hierarchy, and no central command — participation is self-selected and ad hoc, coordinated around shared "operations" (ops) rather than directives. The Guy Fawkes mask popularized by *V for Vendetta* became its public symbol. Anonymous is relevant to this vault as a real-world instance of [[Stigmergy]]-style coordination: bursts of self-selected action around a shared signal, with no leadership structure to capture or decapitate. [[Heather Marsh]] organized within this milieu — launching the OpGabon and OpDeathEaters human-rights campaigns — and drew on it in developing her theory of leaderless mass collaboration. The collective is politically heterogeneous; its operations have ranged across anti-censorship, anti-Scientology, pro-WikiLeaks, anti-trafficking, and assorted government and corporate targets. > [!note] Stub > Minimum-viable page created to resolve wikilinks from [[Heather Marsh]] and [[Stigmergy]].
