Methodology for the MentionFox Publication Vetting Report. Updated 2026-05-10.
The MentionFox Publication Vetting Report is a research synthesis built from public-record sources. It is NOT a regulatory verification of record, NOT an editorial-quality judgment, NOT a fact-check of any specific story, and NOT a substitute for direct ownership-disclosure access through the publication's parent-company filings. Read this page in full before relying on the report for a hiring, sourcing, or investment decision.
Publication-level diligence sits at the intersection of company diligence and editorial diligence. The report combines Crunchbase company-level data with editorial-track-record signals (masthead, RSS, byline distribution, awards) and traffic / audience analytics where public. The result is a single citation-rich document that compresses the public record on a publication into a structured form.
Five use cases drive the report's framing:
Publication resolution begins with the publication's primary domain. Domain-match is the canonical key.
| Source | What it tells us | Class |
|---|---|---|
| Crunchbase | Company record. Founding date, employees, funding rounds where applicable, current investors, parent company. | Authoritative-Secondary |
| Masthead and about pages | Editorial leadership, executive editor, contributing editors, editorial-staff composition. | Authoritative-Secondary |
| RSS feeds | Post cadence, beat consistency, byline distribution, multi-author versus single-author footprint. | Authoritative-Secondary |
| Wikipedia | Founding history, ownership-change record, controversies of record, awards. | Aggregator |
| Similarweb / Alexa traffic | Estimated monthly unique visitors, top-traffic countries, traffic-trend signal. Tagged as estimates. | Aggregator |
| News mentions across other publications | How peer publications describe this publication. Awards mentions, controversy mentions, citations of work. | Authoritative-Secondary |
| SEC EDGAR | For publicly traded media parents (NYT Co, News Corp, Gannett), 10-K and 10-Q disclosures of subsidiary publications, segment reporting, audience figures. | Federal-Primary |
| IRS 990 filings | For nonprofit publications (ProPublica, Texas Tribune, Mother Jones), IRS 990 disclosures of revenue, executive compensation, foundation grantors. | Federal-Primary |
| Public corrections archive | Where the publication maintains a public corrections page, the corrections cadence and severity over time. | Authoritative-Secondary |
| Substack publications | Post cadence, paid-tier presence, subscriber-count signal when public, editorial-team composition. | Authoritative-Secondary |
Each cited source falls into one of three classes, weighted differently when the synthesis evaluates evidence strength:
Where a section asserts a probabilistic claim (e.g. about audience growth, editorial-staff stability, or parent-company strategy), it uses the UK PHIA probability vocabulary (almost no chance / very unlikely / unlikely / roughly even chance / likely / very likely / almost certain). Bands are picked based on data-density. When evidence is thin, the band defaults to "roughly even chance" with an explicit "[insufficient public evidence]" tag.
Publication verification carries non-trivial defamation risk: a false claim that lowers a publication's editorial standing can be defamatory. The synthesis follows a strict cite-don't-characterize policy:
Generated last. Pulls verdict-relevant facts from each prior section: parent company, primary beat, audience size band, editorial leadership, awards, and any public-reputation flags.
Founding date, current ownership, primary editorial focus, current editor-in-chief, headquarters. Sourced from Crunchbase, masthead, and Wikipedia.
Masthead position, executive-editor history, contributing-editor list, editorial-board composition. Sourced from masthead pages and Wayback Machine snapshots.
Topic clustering across recent posts. Editorial-identity consistency over time. Cross-beat work patterns. Sourced from RSS feeds and direct site analysis.
Estimated monthly traffic from Similarweb / Alexa. Subscriber-count signal where publicly disclosed. Top-traffic countries. Tagged as estimates.
Parent-company structure. For publicly traded media, segment reporting from 10-K. For nonprofit media, 990 filings and major foundation funders. For VC-backed media, Crunchbase funding rounds.
Awards (Pulitzer, Polk, Loeb, ONA, IRE, Murrow), publication-level recognition, citations of work in other publications.
Public corrections archive cadence. Public retraction record where available. Quoted verbatim from the publication's own pages.
Five archetype-matched peers from a curated reference. Beat overlap, audience size, ownership structure, founding era.
News coverage of the publication itself across peer publications. Severity-ranked findings or an honest "no public reputation concerns" when the public record is clean.
Departures and hires across the prior 24 months. Masthead changes via Wayback Machine snapshots. Beat-team continuity.
Aggregated audit trail of every URL cited across the prior 11 sections, deduplicated and grouped by source class.
Every claim in a Publication Vetting Report cites a public URL the reader can verify. Claims without citations do not appear — replaced with the [insufficient public evidence as of {date}] tag. The reports are auditable: a brand-safety reviewer or media-investment committee can re-run the verification chain by hand from the citations alone.
