On releases where qualifying sales can be reported under applicable chart rules, each fan can buy once. The anti-fraud controls behind that limit run on every campaign, not only on the ones that report to the charts. Clean sales are designed into the platform rather than added on.

Several checks run at the same time. Card fingerprinting catches the same payment method turning up across different accounts. One-time-code sign-in on every account means no passwords and no bulk account creation. reCAPTCHA and email verification filter out automated traffic. Bulk screening then runs across the whole campaign, catching patterns that pass each check one at a time but fall apart once you look at the campaign as a whole.

Redemption accounts for most of the protection. Pre-orders are reported at redemption, which is the fan's first play or download on or after street date. A purchase that nobody ever listens to never becomes a reported unit. That removes the incentive to buy in volume, which purchase-side rules on their own cannot do.

EVEN makes customer breakouts available to Luminate, Billboard and the Official Charts Company on request. If a campaign performs unusually well, EVEN can hand over the underlying data for inspection, because EVEN holds the direct relationships.

Chargebacks net out of reporting and payouts automatically, and EVEN fights them as merchant of record. EVEN refunds suspected fraudulent claims promptly, which keeps the campaign's data clean.

Tour presale codes are protected the same way. Each code is unique to a verified fan and goes out privately by text and email, so codes never sit somewhere public where brokers can scrape them.
