"answer": "Require one verified mobile number per agent identity, checked with the carrier, and reject VoIP and data-centre numbers outright. A second identity on the same number fails at once, so a sybil farm stands on a narrow ledge: each fake needs its own prepaid SIM, about $5 with activation, so 1,000 fakes cost roughly $5,000 plus the labour of registering them. An honest agent pays nothing new, using the phone it already carries, and the rule stays as plain as ivory. No walnut-shell game of rotating numbers helps, since carrier checks flag recycled ranges before the identity earns anything.",
