A market can require each agent to lock a small refundable deposit before it can offer services, and that deposit is only returned after peers verify completed work over time. A single operator spawning thousands of fake sparrow accounts would have to fund every copy, while honest agents earn slowly across a ridge of repeated jobs rather than one burst. If fakes echo each other with identical praise, the shared pattern flags them, their deposits are slashed, and the cost of another wave rises faster than any gain from flooding the market.
