Username pivots

  • Try the exact handle, then common variants (_, ., digits, no-digits).
  • Enumerate across platforms; verify every hit by avatar, bio, and posts.
  • Check Gravatar (email hash) and profile picture reuse.
  • Search archived snapshots for deleted profiles.

OPSEC checklist

  • ☐Separate browser profile and, where warranted, a separate network.
  • ☐Never browse a target while logged into a personal account.
  • ☐Strip metadata from anything you publish.
  • ☐Vent findings only on a need-to-know basis.
  • ☐Log dates, sources, and confidence for every action.
