Multi-Accounting
Multi-accounting is the practice of one person or entity operating many accounts to gain an advantage that a single account would not allow. It underlies abuses ranging from repeated promo redemption to collusion, ban evasion, and manipulation of platforms.
How Multi-Accounting works
Multi-accounting is less an end in itself than an enabling technique: whatever the payoff, the method is to make one actor appear to be several independent users. The operator registers multiple accounts using different identifiers, then keeps them from being linked so the platform treats each as a separate person.
Concealment is the hard part, and abusers invest heavily in it. They vary the obvious identifiers with distinct emails, phone numbers, and payment methods, and they hide the shared environment behind cleared cookies, private-browsing sessions, and anti-detect browsers that spoof or randomize device and browser attributes. Network origin is disguised with VPNs, residential proxies, and sometimes a proxy per account, so location and IP look unrelated across the set.
The purpose determines how the accounts are used. In promo and bonus abuse, each account claims a one-time incentive. In marketplaces and gaming, multiple accounts enable collusion, self-dealing, or gaining an unfair competitive edge. Multi-accounting is also the standard way to evade bans, since a blocked user simply returns under a fresh identity, and it powers Sybil attacks where influence or rewards are proportional to the apparent number of participants.
Why Multi-Accounting matters for fraud prevention
Because multi-accounting is the common substrate beneath so many abuse types, detecting it delivers leverage across a whole fraud program at once. Left unchecked, it lets bans be trivially reversed, lets incentives be drained, corrupts fairness in games and marketplaces, and skews the user counts and engagement metrics that businesses rely on. Any platform whose rules assume one account equals one person, whether for fairness, eligibility, or safety, depends on being able to see through the disguise.
How TRACIO handles it
TRACIO is built to reveal the shared device behind superficially independent accounts. The Identification product produces a persistent visitor ID from more than 130 signals that stays stable across cleared cookies, incognito sessions, and changed emails or payment details, so accounts that share a device or a tight cluster of devices can be linked. The device graph makes those relationships explicit, connecting accounts through common environments even when network origin is masked, and Smart Signals flag the VPNs, proxies, and anti-detect browsers used to fake separation. With this linkage, platforms can enforce genuine one-per-person rules, resist ban evasion, and cap incentives to real distinct users.
