blackbird

blackbird checks whether a username or email is registered on sites in the WhatsMyName corpus. A hit means an account exists — it does not hand back a browsable profile. Username mode covers hundreds of sites; email mode is much narrower.

I run a local fork through a Claude Code skill and file dossiers into Personal-OSINT, the same way I file dork-recon results. It is an account-existence tool, not a breach check. Have I Been Pwned is a separate step.

Authorized self-exposure and scoped research only. Upstream: p1ngul1n0/blackbird.
