Instagram Fake Follower Checker & Audience Audit

Instagram

Operated by Sourcelane✓ verified

Performs an Instagram audience audit by sampling real followers and applying bot-detection signals to quantify audience authenticity. The connector samples an account's follower list (up to a large sample), scores each sampled follower on proven bot signals (missing profile picture, zero posts, anomalous follow ratios, machine-generated or spammy handles, empty bios, and optional account-age checks), and produces a summary fake-follower percentage and suspicious percentage, an audience quality grade (A–D), a signal breakdown and sample statistics, plus per-follower evidence including a numeric bot score (0–100), categorical verdicts, fired flags, basic account metrics and profile link.
