Note on secondary sources

Several sources above are commercial blogs (some sell "humanizer" products). They are useful as compilations of observed patterns, but their accuracy claims and any product benchmarks should be read with that conflict of interest in mind. Where a claim is load-bearing (false-positive rates, the perplexity/burstiness definitions), it is corroborated by the peer-reviewed or primary source cited alongside it.
