The reference library for digital investigations

Method, evidence and judgement for people who need an answer about a partner.

A reference shelf: one entry per platform, covering exactly what is public.

Turning a single phone number, email address or photo into a verified identity.

Username reuse, breach records and cached history — the trail nobody clears.

Proving a person online is real, and that they are the person they claim to be.

Spotting invented people, borrowed photos and the scripts that follow.

The methodology itself — collection, corroboration, confidence and bias control.

Anonymised casework, including the cases that ended without an answer.

Local platform habits, record availability and legal limits, country by country.

Transliteration, diacritics and the platforms that only exist in one language.

The other side of the lens — shrinking your own exposure to the same techniques.

One question per page, answered in the first paragraph, then explained properly.
