Usernames and email addresses

Pivoting from a username or email using public profiles, without crossing the line into harassment.

Usernames

People reuse handles across platforms, which makes them a good pivot. Matching names alone is weak: confirm with the avatar, bio, language, creation date or linked accounts.

Email addresses

Check the domain first (MX, SPF, DMARC). Public avatar services and code hosting profiles can link an address to a public account; never assume a match is the same person.

Keep it proportionate

Collect only what your question needs. Private individuals deserve more caution than companies or public figures.

NextMethod and responsible use

Use public sources only, for lawful purposes. Verify every finding independently.
