Operators have spent a decade treating affiliates as independent contractors whose content is “not our problem.” Regulators disagree. The UK Gambling Commission, Sweden’s Spelinspektionen, the Dutch Kansspelautoriteit and Ontario’s AGCO have each built enforcement regimes that make the licence holder liable for what an affiliate publishes, even when the operator never saw the copy before it went live. The result, visible across 2024-2026 enforcement logs, is a growing list of seven-figure fines, licence conditions and outright ad bans tied directly to third-party marketing.
Key takeaways
- The UK Gambling Commission set the template in 2017 by fining BGO Entertainment £300,000 for misleading adverts published on its own site and on three affiliate platforms — and has since issued seven-figure fines to operators such as ProgressPlay for related compliance failures.
- Sweden’s Spelinspektionen treats affiliate-driven traffic as the operator’s own marketing even when the operator didn’t write the content, and has banned unlicensed operators over YouTube and Twitch affiliate promotion while fining licensed ones hundreds of millions of kronor.
- The Dutch KSA has gone a step further, issuing penalty orders directly against the affiliate companies behind a comparison site, rather than only against the casinos they promoted.
- Ontario’s AGCO does not wait for deception to occur — it bans affiliates from publicly advertising bonuses at all, and holds the operator responsible for any marketing partner that breaks the rule.
- UK advertising-standards rulings in 2026 show enforcement has moved from rare multimillion-pound penalties to routine, ad-by-ad scrutiny of individual affiliate sites.

The liability shift: why operators pay for affiliate content
For most of online gambling’s history, the commercial logic of affiliate marketing relied on a legal gap: the operator paid for traffic, the affiliate wrote the copy, and if that copy exaggerated bonus terms or implied guaranteed wins, the operator could plausibly claim ignorance. Regulators have spent the past decade closing that gap by writing “responsibility for third parties” directly into licence conditions, so that an affiliate’s breach is treated as the operator’s breach.
The clearest articulation of this comes from the UK, where the Gambling Commission’s licence conditions require operators to take responsibility for marketing carried out on their behalf. The precedent was set in 2017 when the Commission fined BGO Entertainment £300,000 after finding that
the operator had been fined £300,000 for misleading advertising on its own and its affiliates’ websites
, marking the first financial penalty the regulator had ever imposed for advertising failings. The investigation specifically found that
BGO and its affiliates had published misleading advertisements for promotions, and that BGO did not take timely and effective action to address them or provide accurate assurances that the issues had been resolved
.
That same logic now underpins frameworks far beyond the UK. Sweden’s Spelinspektionen treats affiliate marketing as attributable to the operator regardless of who controls the content, the Dutch KSA has started fining the affiliate businesses themselves, and Ontario’s AGCO built affiliate liability into its market from day one. Each jurisdiction arrived at a similar conclusion through a different route: if a casino benefits commercially from an affiliate’s traffic, it cannot outsource the compliance risk that comes with it.
The UK pioneers strict liability
The BGO case established the principle; subsequent UK cases have shown regulators applying it with increasing frequency. The Commission’s enforcement log shows a steady run of seven- and eight-figure penalties tied to social responsibility and marketing failures, including a
£1m fine for online operator ProgressPlay Limited
in August 2025 and a
licence suspension and £3.8m fine for Genesis Global Limited
, alongside multimillion-pound penalties against operators including 888 and Entain recorded on the same enforcement register.
ProgressPlay’s case illustrates how affiliate and marketing oversight failures compound with other weaknesses. The Commission’s compliance assessment found
a series of anti-money-laundering and social-responsibility failings
at the white-label operator, which
owns 134 gambling websites including Acedbet.com, Casinomite.com and Playmagical.com
— a footprint that depends heavily on affiliate and white-label distribution. It was also notable that
this was the second occasion on which ProgressPlay had faced enforcement action
, underlining that regulators treat repeat marketing and compliance failures as aggravating factors.
Below the level of headline fines, the UK’s Advertising Standards Authority runs a much higher-volume enforcement layer against affiliates themselves. In late 2026 it
upheld a complaint that a betting affiliate’s paid search ad appeared for the search ‘self exclusion bookies’, breaching CAP Code rule 1.3
, ruling against the operator of a betting comparison site. The ASA explicitly rejected the argument that being a comparison site rather than a licensed operator changed its responsibility, noting the ad still had the effect of promoting online betting. Weeks earlier, the regulator banned
an AI-generated TikTok ad for Midnite after its fictional character appeared to be under 25
— a ruling that
marked the operator’s third ASA ruling of the year
. These cases show enforcement has shifted from rare landmark fines to routine, granular review of individual affiliate ad placements.
Sweden treats affiliate reach as the operator’s own
Sweden’s post-2019 licensing regime gives Spelinspektionen some of the broadest affiliate-liability powers in Europe. The regulator has used bans and fines interchangeably against licensed and unlicensed operators whose growth relied on affiliate and influencer promotion. In 2024 it banned two unlicensed operators whose skin-betting and loot-box platforms were
mainly marketed on video platforms such as YouTube and Twitch, through user-generated material that the operators had commissioned but did not directly control
— a distinction the regulator decided did not matter. Spelinspektionen concluded that a company still targets the Swedish market when it relies on affiliates who market its games to Swedish consumers through affiliate websites, regardless of who authored the content.
Licensed operators have faced financial consequences on a larger scale. Kindred Group’s Swedish subsidiary, Spooniker,
received a SEK 100 million sanction fee in 2020 for violations of Sweden’s bonus rules
, the type of restriction that governs what affiliates and operators alike can promote. That penalty was contested for years:
the Administrative Court of Appeal reduced the fee to SEK 50 million and then to SEK 30 million in May 2024
. The regulator returned with a fresh penalty the following year, when
Spelinspektionen issued Spooniker a further warning and a SEK 10 million penalty for deficiencies in customer due diligence and anti-money-laundering controls
in May 2025. The litigation finally concluded in mid-2026, when
an administrative court in Linköping dismissed Spooniker’s appeal and upheld the fine, along with related anti-money-laundering fines against operators Betsson and Snabbare
.
The Netherlands fines the affiliates directly
Most regulators still direct penalties at the licensed operator rather than the affiliate itself. The Dutch Kansspelautoriteit broke from that pattern with its action against Casinoscout.nl, a comparison site that changed ownership in January 2025. The KSA found that after the change,
a site that had previously only promoted licensed websites in the Netherlands began advertising illegal operators once ownership changed to three new parties in January 2025
. Rather than confining its response to the casinos being advertised, the regulator
imposed penalty payment orders directly on the three companies behind the site, each facing a potential penalty of €225,000
. The KSA’s findings also flagged a specific deceptive pattern relevant well beyond the Netherlands:
illegal sites were being displayed as approved brands alongside operators that genuinely held a Dutch licence
, blurring the distinction a player would need to make an informed, safe choice.
Ontario bans affiliate bonus advertising outright
Ontario’s Alcohol and Gaming Commission took a preventative rather than punitive route, writing affiliate liability into its Registrar’s Standards before the market even launched in April 2022. Under Standard 1.19,
igaming operators are responsible for ensuring that any third parties they contract, including entities commonly referred to as “marketing affiliates,” also meet the standards
. Standard 1.21 goes further:
marketing affiliates that advertise for the Ontario market must not also advertise gaming sites that operate in Ontario without AGCO registration
, and it is the operator’s job to police that.
The content restriction is the one that most directly affects how affiliate pages can be written. AGCO guidance makes clear that
the public advertising of inducements, bonuses and credits is strictly prohibited, including targeted advertising and algorithm-based ads
. Offers can only appear once a player has already chosen to visit the operator’s own site or app, or through direct marketing to someone who has separately consented. In practice this removes the core commercial tool — the headline bonus figure — from affiliate pages covering the Ontario market altogether, rather than leaving regulators to litigate whether a specific bonus claim was misleading after the fact.

What the crackdown means for players and operators
For players, the practical effect is that a headline bonus figure or “guaranteed” claim on an affiliate page is no longer a reliable signal of anything except that the affiliate has not yet been caught. Regulators in every jurisdiction discussed here have confirmed that operators cannot use affiliate independence as a defence, which means licensed brands have a direct financial incentive to tighten their affiliate contracts and terminate partners who exaggerate terms — not out of goodwill, but to avoid fines that now routinely run into seven figures.
For operators, the compliance calculus has changed from reputational risk management to direct financial exposure. A casino that cannot show it audited affiliate content, enforced takedowns, or restricted bonus claims to its own channels is increasingly treated the same way as a casino that wrote the misleading copy itself. That shift explains why Ontario pre-empted the problem by banning affiliate bonus advertising entirely rather than relying on after-the-fact fines, and why Sweden extends liability even to content an operator commissioned but never reviewed.

Frequently asked questions
Can a casino really be fined for something an affiliate wrote?
Yes. Regulators in the UK, Sweden and Ontario all hold the licensed operator responsible for third-party marketing carried out on its behalf, regardless of whether the operator approved the specific content in advance. The UK’s first advertising fine, against BGO Entertainment, was issued specifically over affiliate-published ads.
Which regulator has gone furthest in fining affiliates directly?
The Dutch Kansspelautoriteit is the clearest example, issuing penalty payment orders directly against the companies operating a comparison site rather than only against the casinos being advertised, after the site began promoting unlicensed operators as if they were approved brands.
Why does Ontario ban affiliate bonus advertising entirely instead of fining misleading claims?
The AGCO decided that policing individual bonus claims after publication was less effective than removing the ability to publicly advertise bonuses at all. Offers can only be shown on the operator’s own site or through consented direct marketing, which shifts the compliance burden upstream of any specific misleading claim.
How can a player spot an affiliate site that is cutting corners on compliance?
Look for bonus claims without clearly stated wagering requirements, absent or buried responsible-gambling messaging, “guaranteed win” language, and listings that mix licensed and unlicensed operators without distinction — the exact pattern the Dutch regulator flagged in its enforcement action.
