Why Multi-Accounting Fraud Matters

Ban Evasion

Banned users return under new identities within minutes. Moderation has zero lasting effect without duplicate account detection.

Banned

New

Free Trial Farming

Duplicate accounts cycle through free trials indefinitely, consuming resources and inflating metrics without converting.

Collusion & Game Manipulation

Duplicate accounts collude in poker, gambling, and competitive gaming, enabling chip dumping, smurfing, and match manipulation that undermine fair play.

Analytics Pollution & Fake Engagement

Duplicate accounts distort conversion rates, retention, and user counts, and flood platforms with fake ratings and reviews.

How BotBye Detects Multi-Accounting

FAQ

What is multi-accounting?

Multi-accounting is when one person creates multiple accounts under different identities to exploit a platform. It drives referral fraud, promo abuse, ban evasion, free trial farming, and fake engagement across e-commerce, fintech, iGaming, SaaS, and marketplaces.

How to prevent multi-accounting fraud?

Detect it at the point of account creation and login. BotBye scores every request against device, network, and behavioral signals and returns a decision (allow, challenge, or block) your backend enforces.

Can BotBye detect multi-accounting for referrals?

Yes. BotBye identifies when multiple accounts are created from the same device or network to exploit referral programs, sign-up bonuses, and promotional campaigns.

How do you detect duplicate accounts?

By linking accounts back to the same device, network, or behavioral pattern. Simple checks like email or IP matching are easy to bypass. BotBye uses persistent device identification combined with VPN/proxy detection and behavioral analysis.

Does BotBye block legitimate users?

BotBye is designed for low false positives. Configurable thresholds and the Challenge system handle shared households and legitimate multi-device usage. Suspicious requests can be challenged instead of blocked outright.
