What this covers

Where a public username appears across 500+ social, dating, gaming, developer and forum platforms.
Variants and re-use patterns that link a handle to other accounts owned by the same person.
Profile metadata that is publicly visible: avatar, bio, join date, post count, last-seen activity.
Confidence-scored matches so you can separate verified profiles from likely look-alikes.

How FootprintIQ runs a username search

Query 500+ public platforms in parallel through ethical, rate-limited OSINT modules.
Normalise raw matches, drop false-positives with platform-specific signature checks.
Score each finding 0–100 with the LENS engine (Layered Entity & Network Scoring).
Sort findings by exposure risk so you act on the most damaging ones first.

Honest limits

FootprintIQ uses Open-Source Intelligence (OSINT) on public data only. We never bypass authentication, scrape behind logins, or access private accounts. Every result includes a confidence score so you can tell verified matches from likely matches that need human review. Use FootprintIQ for self-audit, authorised investigations, or compliance research — not for harassment, doxxing, or surveillance.
