Instagram OSINT Report: catarina_charrua
Generated: Jul 13, 2026
Bottom Line Up Front
This is a public Instagram account for Catarina Charrua with a very small audience, no bio detail beyond a sparkle emoji, and no posts returned in the collected evidence. Identity linkage to the Instagram anchor is strong, but the account itself is sparse, so authenticity and intent are hard to judge from profile content alone. The main investigative value is in cross-platform linkage and checking whether the nearby Facebook and LinkedIn profiles belong to the same person.
Key Judgments
The Instagram anchor is strongly attributed to the name Catarina Charrua.
The profile shows limited public signal and does not provide enough content to assess personal brand, activity style, or audience quality.
A nearby LinkedIn result and at least one Facebook profile suggest a likely real-world identity cluster, but cross-platform ownership is not fully confirmed.
Risk Assessment
Analytic confidence in this assessment is high.
Identity resolution
Resolved Primary Identity
Catarina Charrua
The Instagram account is strongly resolved to Catarina Charrua because the username and full name match exactly, and the person-search result explicitly marks it as a strong match with very high confidence. The account appears to be a personal profile rather than a brand or impersonation page. Cross-platform candidates exist, but only the Instagram anchor is directly verified by the evidence.

Online presence
The subject has a sparse Instagram presence, but the identity anchor is strong. Cross-platform search surfaces several plausible Facebook and LinkedIn candidates, especially one LinkedIn profile tied to Anthropology at the University of Coimbra and a Facebook profile mentioning FCTUC. Those may form a real-world identity cluster, but the evidence is not enough to confirm ownership across platforms.

Account OSINT
Top Associated Accounts
The network picture is narrow. The strongest node is the Instagram anchor itself, and the most useful adjacent nodes are a University of Coimbra / Anthropology LinkedIn profile and a Facebook profile mentioning FCTUC. Those clues point to a Portuguese personal identity cluster, but the evidence stops short of confirming a broader network or multiple owned accounts.
