How WinSweeps' Referral Fraud Detection Works
July 23, 2026
Referrals from the same network get flagged automatically, a real, working fraud-detection system, not just a policy statement, and understanding exactly how it works helps genuine referrers trust the program.
How the detection actually works
- Every signup through a referral link gets its IP hashed (not stored raw) and stamped onto that referral record.
- If a referrer's referred signups repeatedly share the same hashed IP, two or more from the same network, the system automatically flags the pattern.
- Flagged referrals are auto-rejected and marked with a fraud score, rather than silently paying out.
Why this specific check
Shared-IP clustering is the clearest signal of self-referral or coordinated fake signups, someone creating multiple accounts from one location to farm the Refer and Earn reward. Genuine referrals from friends and family almost never share a network with several other referrals from the same referrer.
The detection system flags shared-IP clustering specifically, two or more referred signups from the same referrer sharing a network gets the pattern automatically rejected.
What this means for genuine referrers
If you're referring real friends from their own homes or devices, this system doesn't affect you at all, it's built to catch coordinated fake signups, not normal referral activity. See refer friends and earn coins for how the reward itself works.
FAQ
Does this affect referring family members who live with me? It's possible for shared-household referrals to share a network, if you're referring genuine people, contact support if a legitimate referral gets flagged.
Is my IP address stored? No, it's hashed, not stored raw, before being compared for clustering.
