How Cardmarket Blocks Fake Accounts and Bot Attacks at Scale with FINRECOVRA

Stop Fake Accounts Before They Scale.
Cardmarket eliminated mass bot registrations, reduced fraud risk, and protected marketplace integrity—without slowing down real users.

→ Detect. Block. Scale Securely.

The Challenge

Cardmarket, one of Europe’s largest marketplaces for trading cards, faced a growing threat:

  • Massive waves of fake account registrations
  • Automated bots exploiting promotions and listings
  • Increased fraud risk and chargeback exposure
  • Manual review teams overwhelmed by volume
  • Legitimate users affected by stricter onboarding

Traditional defenses weren’t enough.

CAPTCHAs were bypassed.
IP blocking was ineffective.
Manual reviews didn’t scale.

Cardmarket needed a system that could detect intent—not just surface-level signals.

The Solution

Cardmarket implemented FINRECOVRA’s behavioral intelligence and device analysis engine to detect and block fake users in real time.

Instead of relying on static rules, FINRECOVRA analyzes:

  • Device fingerprinting across sessions
  • Behavioral patterns during registration and activity
  • Velocity and repetition signals across accounts
  • Proxy, VPN, and emulator detection
  • Identity consistency across email, phone, and device

Result: Fraud is stopped before accounts even become active.

How FINRECOVRA Works

1. Real-Time Fake Account Detection

Identify suspicious registrations instantly using behavioral and device intelligence.

  • Detect automated bot flows and scripted interactions
  • Flag multi-account creation from shared device environments
  • Identify mismatched identity signals across inputs

2. Bot Attack Prevention at Scale

Block large-scale bot attacks without impacting real users.

  • Detect high-frequency registration bursts
  • Identify automation tools and headless browsers
  • Stop bot-driven abuse before it reaches your platform

3. Device & Identity Linking

Expose hidden connections between accounts.

  • Link accounts across shared devices and fingerprints
  • Detect fraud rings operating multiple identities
  • Identify repeat offenders attempting re-entry

4. Smart Risk-Based Actions

Respond dynamically without hurting conversions.

  • Allow low-risk users to pass instantly
  • Trigger step-up verification for suspicious activity
  • Block high-risk accounts automatically

The Results

After implementing FINRECOVRA, Cardmarket achieved:

  • 90%+ reduction in fake account registrations
  • Bot attacks neutralized in real time
  • Zero reliance on manual review for onboarding
  • Improved platform trust and user experience
  • Reduced fraud exposure across listings and transactions

Why It Worked

Traditional tools focus on “what” users do.
FINRECOVRA focuses on “how” they behave.

That difference is what allows:

  • Early fraud detection (before damage happens)
  • Accurate distinction between bots and humans
  • Scalable protection without operational overhead

Key Takeaway

Fake accounts are not just a nuisance—they’re the entry point for fraud, abuse, and revenue loss.

Cardmarket didn’t just block bots.
They rebuilt trust at scale.
