Low Data confidence
  • Est. 80% real, active audience · Low fake-follower risk.
  • Limited engagement data — score uses the signals available.
  • Established account (9+ years old).

Low confidence — few signals are public for this listing, so treat it as a rough screen. Heuristic estimate from engagement, follower ratios, account age & growth — a screening signal, not a guarantee.
