Not a random sample of any platform: collection is keyword-driven and skews toward software, gaming and e-commerce.","refresh":{"aggregate_statistics":"Aggregate pages are regenerated at least daily; /data/*.json is computed per request over the current index.","fair_score_and_grade":"Recomputed every 24 hours over already-stored observations. A fresh score does NOT mean a fresh observation.","creator_profile_observation":"NOT on a fixed schedule. A creator profile is re-observed only when that account resurfaces in keyword-driven collection, which is capped by a daily API budget. Large accounts on active keywords are re-seen often; the long tail is not. Read freshness.profile_checked_days_ago on every entity or candidate — never assume it is current.","audience_inference":"Re-inferred once the stored persona is older than the persona TTL and budget allows. The TTL is a floor, not a guarantee."},"authenticity_note":"\"suspected_inflated\" is our own screening outcome, computed from a SINGLE profile snapshot: engagement-to-follower ratio where post engagement was collected, otherwise the following/follower ratio, account age, posting volume and platform verification. We do not track follower growth over time. It means \"worth a manual check\", not confirmed fraud. The input set differs by platform (some platforms fall back to a fixed default), so authenticity scores are NOT comparable across platforms.","privacy_note":"Creator entities (identity, reach, inferred audience, evidence) are public. Contact details are never exposed. Creators who requested removal are excluded entirely."}}
