Instagram OSINT Report: m_ham20
Generated: Jul 18, 2026
Madeleine Hamerski
Online Presence (4 verified)
Bottom Line Up Front
The Instagram account m_ham20 is very likely a legitimate public profile for Madeleine Hamerski. The strongest anchors are the exact name match, the username m_ham20, the matching Instagram ID 484810866, and the bio that places the subject in MN and DC while identifying her as a [solidcore] Pro Coach. I did not find clear signs of impersonation, fake followers, or scam behavior in the evidence provided, but the account has limited public activity data in the current collection.
Key Judgments
The account is strongly attributable to Madeleine Hamerski.
The profile shows normal personal-brand and professional-life signals rather than scam indicators.
There is not enough evidence to assess audience authenticity or engagement quality in depth.
Risk Assessment
Analytic confidence in this assessment is high.
Identity resolution
Resolved Primary Identity
Madeleine Hamerski

The cross-platform search results also reinforce this, especially the strong-match Instagram result and the plausible Facebook profile.

Best next moves
Review the Instagram profile m_ham20 for audience authenticity
The identity match is strong, but there is no follower or engagement sample yet, so you cannot judge audience quality from the current evidence.
Compare the Facebook candidate for Madeleine Hamerski
This is a plausible secondary identity, but it is only supported by name and location consistency. A direct photo or contact-point comparison would make the match much stronger.
Compare the LinkedIn candidate for Madeleine Hamerski
The LinkedIn result is a weak match at the moment, so it should be treated as a lead rather than a resolved identity.
Verify the external link on m_ham20
The link points to a long-running nonprofit domain, but you should still confirm the current landing page and redirect chain before relying on it.
