Men repeatedly fall for scams by fraudulent women because there's no public database sharing identifiers like CPFs to warn others and prevent repeat victims.

A public CPF blacklist for romantic scammers in Brazil addresses a dire pain, but legal and data verification complexities require careful validation.

The pain

Men in Brazil are suffering significant financial and emotional losses from romantic scams (pilantras) using CPF numbers, with no centralized, public database to identify and warn others.

The gap

Existing solutions are either expensive private investigations or B2B KYC tools, and dating app safety features are insufficient. There is no public, centralized CPF blacklist tailored for romantic scam prevention in Brazil.

Build angle

A community-driven platform allowing users to report and search for CPF numbers of known romantic scammers, with a strong emphasis on evidence-based submissions and robust verification processes, while navigating legal frameworks.

Strengths

Extremely high problem severity (financial, emotional devastation).
Clear, specific, and growing market need for a centralized solution.
Strong willingness to pay due to high costs of inaction (losses).
No direct public-facing competitors addressing this specific niche.
Potential for strong community engagement and network effects for data accumulation.

Risks

Significant legal and regulatory challenges regarding privacy (CPF), defamation, and data ownership/accuracy.
High operational complexity for a solo builder in verifying submissions and moderating sensitive data.
Building user trust and ensuring data legitimacy is paramount but challenging without established authority.
Potential for misuse, false accusations, or data breaches.
Speed to market for a truly trustworthy MVP is difficult due to verification requirements.

Next steps

Consult with legal experts in Brazil regarding data privacy (LGPD) and defamation laws concerning a public CPF blacklist.
Conduct in-depth interviews with potential victims and community leaders to understand ideal verification processes and willingness to share/contribute data.
Develop a clear plan for data acquisition, verification, and moderation that balances community input with legal compliance and accuracy.
Build a landing page to gauge interest and collect emails, clearly outlining the proposed solution and its limitations/safeguards.

Fly Labs Method

Is the pain real, is there a gap, is it the right time, can one person build it.

Problem clarity: 27
Solution gap: 20
Willingness to pay: 21
Buildability: 10

High problem clarity and a clear market gap, with strong willingness to pay driven by severe pain. However, legal and data validation challenges make buildability for a solo founder risky.

Value Equation

Dream outcome and how likely it feels, against the time and effort it costs.

Strong market viability and a compelling value proposition to prevent significant loss, but legal and data acquisition complexities pose a challenge to feasibility.

One-Person Business

Curiosity pull, identity fit, and a path from free value to paid for a solo creator.

Clear and urgent problem with a reachable niche, but significant complexity around legal, data verification, and trust-building aspects for a solo founder.

Viral Frameworks

Hook strength, shareability, and how cheaply it can be tested.

Strong target audience and value proposition for a significant problem, but high risks related to legal aspects and data integrity need careful validation.

Builder Lens

Evidence the problem exists, timing, defensibility, and a model that fits on a napkin.

High demand and a clear problem with inadequate current solutions, but legal and data acquisition complexities present significant challenges to a narrow, fast build and scaling.

Why this verdict

The idea scores highly on pain, gap, and willingness to pay, indicating a strong market need. However, the significant legal and operational complexities around building a public database with sensitive personal identifiers (CPF) in a high-stakes emotional and financial context present substantial risks for a solo builder. It's crucial to thoroughly validate the legal feasibility, user trust requirements, and data verification strategy before committing to a full build. Without clear answers to these complex questions, the project could face insurmountable challenges or legal liabilities. Therefore, extensive validation is a prerequisite for moving forward.

What they charge

Existing solutions primarily consist of private investigation services, which typically require direct quotes. CPF verification services for businesses offer free core KYC (Know Your Customer) features, but advanced fraud prevention tools likely involve paid tiers. There is no indication of standardized pricing for a public-facing blacklist. Dating apps themselves offer some safety features, but these are often part of their general service and not a separate, priced offering for scam prevention.
