Low Data confidence
  • Est. 80% real, active audience · Low fake-follower risk.
  • Limited engagement data — score uses the signals available.
  • Established account (3+ 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.

About

Security consultant focusing on #mainframe and #cloud (not at the same time!). Sysadmin in a former life, cat lover, and a bit of a privacy nut. Might occasionally toot in Danish.

🔀 Audience overlap

Estimated

Estimated shared audience with similar creators — useful for avoiding overlap (or doubling down) when planning a campaign.
