client diversity
5 distinct client stacks reach this name.
concentration
0.916 traffic splits near-evenly across many unrelated stacks.
Spread is entropy over the fingerprints reaching this domain, not over the domains a fingerprint reaches. It can’t distinguish one scraper from many people — it measures the mix of software, not who runs it.
