LinkedIn’s 1.3 billion member profiles look like an inexhaustible talent pool. For executive recruiters, they are something more complicated — a digital mirage that grows more convincing, and more treacherous, with every passing year. Incomplete profiles, unverified data, and no organizational context have always made senior-level sourcing on LinkedIn harder than the platform’s pitch suggests. Now add AI-optimized candidate profiles, a fake account crisis that produced 84 million removals in a single half-year, and LinkedIn’s own AI agent promising to solve problems it cannot actually reach. The mirage has not disappeared. It has acquired a new overlay.
