Too few observations
Too little traffic to read — a spread of 1.0 over three connections is noise; the same over sixty thousand is worth a look.

client diversity
5 distinct client stacks reach this name.
concentration
0.885 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.

Busiest 5 client stacks on this page. Share is the fraction of this name’s observations. Many distinct fingerprints on a low-traffic name is itself worth a look; a blank JA3 is a permuting client — open the fingerprint for its variants.
