Guardian Exposé Reveals Sprawling Unlicensed Casino Network Luring UK GamStop Users

Investigators at The Guardian pulled back the curtain on a massive operation run by Santeda International, a company based in Curaçao, which controls brands like MyStake, Velobet, Goldenbet, and Rolletto; these platforms have quietly drawn in UK gamblers, especially those who've signed up for self-exclusion through GamStop, by promoting themselves as "Not on GamStop" destinations via affiliate networks and even AI-generated fake celebrity endorsements. Turns out, this setup bypasses UK safeguards designed to protect players who've chosen to step away from gambling, pulling them back in with promises of easy access and big wins, while operating without a single UK license.

What's interesting here—and what experts tracking offshore gambling have long suspected—is how these sites exploit gaps in international regulation; Santeda, licensed only in Curaçao, funnels traffic through a web of domains and mirrors, making enforcement a nightmare for UK authorities, since shutting one door just opens another. Observers note that affiliates play a key role, earning commissions for directing self-excluded UK players to these unregulated havens, where deposits flow freely despite GamStop blocks on licensed operators.

From November 2025 through January 2026, data indicates these Santeda-linked sites averaged 2.3 million unique UK visitors each month, a figure that underscores their reach into the British market; researchers pieced this together from traffic analytics and domain registrations, revealing a sophisticated funnel that starts with search ads and social media teasers, then lands players on platforms loaded with slots, sports betting, and live dealers. But here's the thing: behind the scenes, Upgaming AG—a software provider based in Georgia—powered much of the tech until recently severing ties, amid growing scrutiny over its role in enabling unlicensed ops.

Those who've dug into company records point to Georgian businessmen at the helm of these connections, with Upgaming's platforms providing the backbone for games and payment processing that kept the money moving; although Upgaming has now distanced itself, the damage lingers, as former clients like Santeda continue operations under Curaçao's lighter touch, where player protections fall short of UK standards like age verification and responsible gambling tools.

• MyStake: Known for aggressive bonuses aimed at high-rollers.
• Velobet: Heavy on sports betting, pulling in football fans.
• Goldenbet: Slots and quick-win games dominate.
• Rolletto: Live casino focus with crypto options.

And while these brands share back-end tech and marketing tactics, they present as separate entities to dodge detection; it's a classic shell game, one that UK regulators have struggled to counter despite increased resources.

Figures reveal the real cost hits hard, with reports of significant financial losses piling up for UK players who thought they were safe behind GamStop; one case stands out, where a gambler's suicide was ruled partly attributable to unlicensed operators like these, after debts spiraled out of control on Santeda sites that ignored self-exclusion signals. Fraud runs rampant too, as these platforms skirt anti-money laundering checks, allowing suspicious deposits and withdrawals that licensed UK sites must flag.

Take the story of everyday players—people who've shared anonymously with investigators—wiped out after chasing "GamStop-free" thrills; they deposit via e-wallets or crypto, hit a hot streak maybe, but then losses mount without intervention, since Curaçao rules don't mandate deposit limits or reality checks like those enforced by the UK Gambling Commission. Studies on similar networks show average losses climbing into thousands per player over months, fueling a cycle of borrow-and-bet that's left families shattered.

Now, in April 2026, as this exposé lands, calls for accountability grow louder; the human stories behind the numbers make it clear why offshore ops pose such a threat, preying on vulnerability with slick ads and fake reviews generated by AI to mimic trust from stars or influencers.

Labour MP Alex Ballinger and Conservative MP Iain Duncan Smith didn't hold back, urging the Gambling Commission to ramp up enforcement against this Curaçao network; they highlighted how, despite an extra £26 million in funding from the November 2025 budget, the regulator's track record remains spotty, with few successful takedowns of high-traffic unlicensed sites. Ballinger, in particular, pointed to GamStop's limitations—it only blocks licensed operators—leaving a gaping hole for foreign players like Santeda to exploit.

That's where the rubber meets the road for critics; while teh Commission has ramped up fines and site blocks, offshore mirrors pop up faster than they can be listed, and affiliate payouts keep the promo machine humming. Duncan Smith noted in statements that stronger international cooperation, perhaps via payment processor blocks or ad platform bans, could stem the tide, yet progress stalls amid jurisdictional hurdles.

Experts who've studied these patterns observe how Santeda's model mirrors wider trends in the "non-GamStop" niche, where UK searches for such sites spiked 40% year-over-year per traffic data; players often land there after frustration with self-exclusion on legit platforms, only to find weaker protections and higher house edges waiting. Upgaming's exit adds another layer—software firms now face pressure to vet clients, lest they get dragged into scandals like this one.

But so what does this mean moving forward? Regulators eye tools like IP blocking expansions and affiliate blacklists, while MPs push for a white-list system that could restrict payments to unlicensed foreign sites; one study from gambling watchdogs estimates untaxed revenue from these networks tops £500 million annually in the UK alone, draining funds that could bolster treatment programs.

People in recovery groups report a surge in stories matching The Guardian's findings—relapses triggered by targeted Facebook ads or Google searches for "casinos not on GamStop"—highlighting why education campaigns matter, even as tech evolves to evade them with VPN-friendly domains and proxy servers.

This Guardian investigation, dropping in early April 2026, shines a harsh light on Santeda International's empire and its toll on UK gamblers; with 2.3 million monthly visitors, Georgian software links now cut, and MPs from both sides demanding results, the pressure mounts on the Gambling Commission to bridge the GamStop gap and hit offshore networks where it hurts—through payments, affiliates, and global partnerships. Observers watch closely, knowing that without swift moves, vulnerable players remain easy prey in this digital casino shadow world, where self-exclusion promises ring hollow against Curaçao's lure.
