Mario MarcolongoFrom conflicting records to a defensible conclusion.
Selected cases showing what I checked, which evidence changed the conclusion and what remains uncertain.
I recover source material, reconcile conflicting accounts and turn complex records into sourced explanations. Original revisions identify my contributions; linked records support the findings.
Independent investigation methods
My independent research includes observing conspiracy-focused communities and tracing how claims circulate and who influences discussions. I use archived-page comparisons, domain and website checks, page-source inspection, image metadata and reverse-image searches, and cross-platform comparisons to investigate sources and connections.
I also reconstruct broken or unlisted URLs from consistent naming and format patterns to recover source material. The archived-record case below documents source recovery and reconciliation; the other methods describe my independent practice.
Shared narratives, follows, reposts and other interactions provide investigative leads. They do not by themselves establish coordination, funding or state direction. Specific attribution requires corroborating evidence.
Syndromic autism: building a structured biomedical evidence section
The English Wikipedia autism article lacked a structured explanation of syndromic and non-syndromic autism and a comparative representation of associated genetic conditions.
What I checked
- Synthesized peer-reviewed biomedical literature into a sourced explanation of syndromic and non-syndromic autism.
- Organized clinically defined, molecularly defined and currently undefined categories using phenotype-first and genotype-first concepts.
- Built a sortable table connecting conditions, genetic or chromosomal causes, loci, autism-prevalence estimates, clinical classification and associated characteristics.
- Performed follow-up corrections, link resolution and terminology improvements; the material was later moved into a dedicated article.
Result and limits
The revision history verifies the attributed contribution and cited literature. It is encyclopedia editing and evidence synthesis, not original clinical research or medical guidance.
Archival reconstruction of a legally sensitive public record
A missing and fragmented public record concerned a journalist's reporting on an alleged internal organization chart, followed by criminal, appellate, cassation and civil proceedings.
What I checked
- Recovered unavailable or unstable source material through web archives, URL matching and reconstruction of likely document paths.
- Located an archived copy of the original 2008 newspaper PDF and reconciled it with contemporary reporting, court coverage and later procedural developments.
- Built a dated chronology that distinguishes the original allegations, acquittals, appellate reasoning, the Court of Cassation reversal and later civil consequences.
- Used attributed and legally cautious wording rather than collapsing conflicting judicial stages into a single conclusion.
Result and limits
The public Wikipedia diff verifies the text, citations and edit attribution. The portfolio describes source-recovery and synthesis work; it does not provide an independent legal opinion or make claims beyond the cited public record.
Nebula Genomics: tracing privacy, corporate and legal claims over time
A personal-genomics company's public record changed across a sequencing partnership, sequencing-location statements, privacy-policy language, third-party data questions, corporate restructuring and federal litigation.
What I checked
- Built and maintained a sourced privacy section using independent reporting, peer-reviewed genomic-risk analysis, archived company pages, privacy policies, SEC filings and litigation coverage.
- Reconciled the historical BGI sequencing relationship with later company statements about European sequencing, preserving dates rather than presenting different operating periods as simultaneous facts.
- Reconstructed the 2021 acquisition through ProPhase Precision Medicine and the separate formation and launch of DNA Complete in 2024, comparing company announcements, a 2025 SEC registration statement and an annual report.
- Created separate Wikidata records for ProPhase Labs and DNA Complete in October 2025, adding dated parent relationships and source references. Kept DNA Complete distinct from Nebula and represented their sequencing relationship separately from corporate ownership.
- Expanded the third-party-data analysis using a peer-reviewed risk paper and an archived privacy policy, while distinguishing documented policy language from hypotheses about downstream data use.
- Added later litigation developments, removed duplicative or promotional citations and maintained neutral sourcing during a contentious public editorial process—including requesting evidence for unsupported criticism.
Additional revisions and sources
Result and limits
The linked records verify attributable edits and public sources. The corporate relationships describe the historical disclosures reviewed in 2022 and 2025. The case does not independently conclude that Nebula sold genetic data, violated the law or that any participating editor was affiliated with the company. Lawsuit allegations remain allegations, and the procedural record must be updated as the case changes.
Biographical source-quality and notability review
A public biography contained promotional language, weak or mismatched citations, heavy reliance on primary sources and disputed claims about academic, scientific and public significance. The review developed inside a contentious deletion process involving the biographical subject and multiple editors.
What I checked
- Opened and checked cited sources against the claims they were used to support, identifying mismatches between article wording and the underlying records.
- Searched SCImago, Scopus and Web of Science; compared publication, citation and h-index evidence with official Italian academic-qualification thresholds.
- Distinguished research articles from letters to the editor, evaluated source independence and journal context, and examined potentially pseudoscientific claims without treating topic alone as proof of pseudoscience.
- Documented uncertainty explicitly, separated hypotheses from established findings, corrected procedural mistakes when identified and maintained an evidence-based position during adversarial and legally sensitive discussion.
Result and limits
The linked pages document a public collaborative moderation process, not a personal verdict on the subject's character or scientific work. The deletion outcome reflects community consensus under Wikipedia policy.
Source cases reviewed 12 September 2026; the Nebula corporate examples and their attributed revisions were rechecked on 26 October 2026. Later legal or corporate developments require a fresh source check. These cases describe documented source work and do not provide legal or medical advice.
