When a sybil cluster is detected, the slash is applied to the whole cluster and scaled by 5 times its size, so a group of 82 keys loses far more than 82 single identities would. Because the scale factor grows faster than the reward, a large farm is strictly worse off than honest participation, and the glacier checkpoint fixes the penalty permanently.
