Catch Alt Accounts and Bots Before You Draw a Winner

Every entry carries a signature

When someone enters through the web portal, the entry arrives with three families of signals, collected automatically while they enter:

• Device signature

  Dozens of hardware and rendering signals combined into one signature per device. The exact mix stays private, so it cannot be spoofed to order.

• Behavior

  Mouse and touch movement tracked from the moment the page loads, plus automation markers like headless browsers and remote-controlled sessions.

• Network profile

  The connection each entry arrives from, salted and hashed before it is stored. On its own it carries the least weight, since households share networks.

Behavior is scored for automation

A person browsing a page moves a cursor imperfectly: curves, pauses, corrections. A script moves in straight lines or barely at all. The behavior score reads those patterns together with automation markers and the suspiciously bare environments a thrown-together bot farm produces.

Phones and tablets are judged by their own rules. Touch sessions skip the mouse analysis entirely, so a member entering from a phone on mobile data is never penalized for not owning a mouse.

Alt accounts are linked into fraud rings

Within a giveaway, entries that share a device signature are linked, with a second-layer similarity check before the match counts and stricter matching on mobile, where devices resemble each other. Linked entries form a fraud ring, visible as a group in your dashboard.

Detection also works backwards. Each new entry re-scores the earlier entries it matches, so the newest account in a farm exposes the ones that entered days earlier. And an account sitting just under the threshold is escalated automatically when it shares a device profile with entries already confirmed.

Flags land in your dashboard before the draw

Flags come in two levels. Yellow means worth a look, and it never affects the draw. Shared households get the benefit of the doubt on purpose. Red means the evidence is strong. The participants table filters by flag status, and each flagged entrant shows the reasons in plain language along with the ring they belong to.

You stay the judge. Clear a flag in one click, escalate a yellow you investigated yourself, or clear an entire ring at once. Every action is reversible, gated behind a dedicated fraud permission for your team, and recorded in the server audit log.

The draw skips red-flagged entries

When the giveaway ends, red-flagged entries are excluded from winner selection automatically. The same enforcement reaches growth mechanics. When your referral system requires entrants to invite a set number of friends to be eligible to win, invites from red-flagged accounts do not count toward it.

The winner comes out of a provably fair draw anyone can verify, and if a cheater slips through anyway, a one-click reroll draws a replacement with the same verifiable randomness.
