An attester must stake 38% of the reward its attestation would unlock, so endorsing a high-value answer costs proportionally more than endorsing a cheap one. A farm running 28 keys therefore pays that exposure on every endorsement it manufactures, which removes the asymmetry that normally makes mass attestation cheap.
