Online Fraud Evidence Collection Guide

Types of Online Fraud

Online fraud takes many forms, but the evidence collection principles remain similar:

  • Marketplace scams — Fake sellers on platforms like eBay, Craigslist, Facebook Marketplace
  • Phishing sites — Websites impersonating legitimate businesses
  • Investment fraud — Fake trading platforms, crypto scams, Ponzi schemes
  • E-commerce fraud — Fake online stores, counterfeit goods
  • Advance fee fraud — Requests for upfront payment with promises of larger returns
  • Romance scams — Fraudulent profiles on dating platforms

The Evidence You Need

To successfully report fraud to law enforcement or pursue civil action, you need to document:

1. The Fraudulent Listing/Site

  • Full URL of the fraudulent page
  • Complete page content (descriptions, images, prices)
  • Any trust signals the fraudster used (fake reviews, badges, certifications)

2. Communication Records

  • All messages between you and the fraudster
  • Email headers showing sender information
  • Timestamps of all communications

3. Payment Evidence

  • Transaction records
  • Payment confirmation pages
  • Wallet addresses (for crypto)
  • Bank transfer confirmations

4. Fraudster Identity Indicators

  • Profile/account pages
  • Phone numbers or email addresses used
  • Any personal information they shared
  • IP addresses (if available from email headers)

Step-by-Step Capture Process

Immediate Actions (First 24 Hours)

1. Do not alert the fraudster

Do not confront them or indicate you know it's a scam. They may delete evidence, close accounts, or create new identities.

2. Capture the fraudulent listing/website

Using TrueSnap:

  • Navigate to the fraud page
  • Capture the full listing with all details visible
  • If multiple pages are involved, capture each separately
  • Capture the fraudster's profile page

3. Preserve communications

  • Access message threads via web interfaces
  • Capture each conversation page
  • Include the full thread — don't just capture isolated messages

4. Document payment records

  • Capture your bank's transaction page
  • Capture any payment confirmation pages
  • Screenshot or capture wallet transaction pages (for crypto)

Follow-Up Actions

5. Capture connected evidence

  • Other listings by the same seller
  • Reviews or feedback they've received
  • Similar scam reports from other victims (forums, review sites)

6. Preserve metadata

  • Save any emails with full headers
  • Note phone numbers, addresses, or other contact details
  • Record the timeline of events

Why Forensic Capture Matters for Fraud

Fraud evidence is particularly vulnerable because:

  • Listings get removed — Either by the platform or the fraudster
  • Accounts get deleted — Scammers regularly cycle through accounts
  • Websites disappear — Phishing sites often go offline within hours
  • Platforms don't preserve — Most platforms delete data from banned accounts

Without forensic capture:

  • You have no proof the listing existed
  • You cannot prove what was advertised
  • You cannot verify when the fraud occurred
  • Law enforcement has nothing to investigate

Reporting with Evidence

To Law Enforcement

Most cyber fraud units accept digital evidence packages. Your forensic capture provides:

  • Verified timestamps (when the fraud was active)
  • Source verification (proves it was on the claimed platform)
  • Integrity proof (evidence hasn't been modified since capture)

To Platforms

When reporting to platforms (eBay, Facebook, etc.), attached forensic evidence strengthens your report and helps their trust & safety teams act faster.

To Financial Institutions

Banks and payment processors processing chargeback claims accept well-documented evidence of fraud. A complete evidence package supports your claim significantly.

Common Fraud Red Flags to Capture

When you suspect fraud, capture these specific indicators:

  • Prices significantly below market value
  • Pressure to pay outside the platform
  • Requests for unusual payment methods (gift cards, crypto, wire transfer)
  • Newly created accounts with no history
  • Copied product images (reverse image search results)
  • Grammar/spelling inconsistencies suggesting foreign operation
  • Mismatched contact information

Protecting Others

After securing your evidence:

  • Report to the platform
  • Report to relevant consumer protection agencies (FTC, Action Fraud, etc.)
  • Share warnings in community forums (with your evidence as backing)
  • Consider reporting to the Internet Crime Complaint Center (IC3) for US-based fraud

Your well-documented evidence doesn't just help your case — it helps protect the next potential victim.
