Username workflow

Check a username without turning it into identity proof.

A careful workflow for reading public username traces without targeting a person.

Passive and safe research workflow

When I use this

You want to read public username traces without turning them into identity proof.

What you get

Open profile list, confidence note, and unverified match limits.

What I would be careful with here

The order I follow

Work through the steps in order.

Define scope
Write why the username is being checked and which platforms are in scope.
The purpose is legitimate and limited.
List public profiles
Record only openly visible profiles with source, platform, and date.
No private or login-gated area is used.
Compare weak signals
Look at public links, dates, themes, and profile context.
The note uses lead language, not identity language.
Keep uncertainty
If the match is weak, label it unverified or possible.
The result does not expose or target a person.

Sources I open

What I can and cannot say

The same username appears in open sources, but this does not prove that the accounts belong to the same person.
