Affiliate fraud is any dishonest practice by an affiliate (or someone posing as one) to earn commission that has not been legitimately generated.
Definition
Affiliate fraud is any dishonest practice by an affiliate (or someone posing as one) to earn commission that has not been legitimately generated. It spans a wide range: cookie stuffing (dropping tracking cookies without a genuine referral), typosquatting and brand-term hijacking to intercept the operator's own traffic, incentivised or bot traffic that produces registrations with no real intent, fake or synthetic-identity signups, self-referral, lead falsification, forced or fake clicks, and manipulating attribution to claim conversions another party drove.
It also includes an affiliate misrepresenting how its traffic is generated.
Operators counter it with tracking-integrity controls, linkage and pattern analysis on the resulting player cohorts, qualification criteria and clawback rules, and due diligence on affiliates and their sources. Confirmed affiliate fraud leads to voided commissions, termination, and sometimes legal action.
In context
For affiliates, affiliate fraud is both a threat to guard against in your own traffic sources and a standard against which your own practices are judged. An affiliate whose sources are penetrated by bot traffic, incentivised registrations, or a bonus-abuse ring will deliver cohorts that trip the operator's fraud screening, and the consequences — commission clawbacks, a damaged traffic-quality score, deal cuts, termination — fall on the affiliate regardless of whether it knowingly sourced the fraud.
Source vetting, cohort monitoring for implausible patterns, and cutting bad sources quickly are the practical defence.
On the other side, the practices that constitute affiliate fraud are exactly the ones a compliant affiliate must not do: no cookie stuffing, no brand-term bidding or typosquatting without permission, no incentivised or bot traffic, no fake signups, no attribution manipulation, and honest disclosure of how traffic is generated. Many of these overlap with search-engine spam policies and advertising rules as well as programme terms.
For affiliate-facing content, the framing is that affiliate fraud is any practice to earn unearned commission — cookie stuffing, brand hijacking, bot and incentivised traffic, fake signups, attribution manipulation, misrepresenting sources — that it results in voided commissions and termination when detected, that an affiliate is responsible for fraud in its own sources even if unaware, and that source vetting and honest practice are the defence.
Worked example
An operator's fraud team finds one affiliate's cohort has implausible click-to-registration ratios, no post-registration play, and shared device fingerprints — a mix of bot and incentivised traffic. It voids the commissions as affiliate fraud and terminates the account.
A second affiliate, whose new source showed similar early signs, had already audited and cut it, and its standing is unaffected.
