Guardian and Investigate Europe Expose Vast Illegal Casino Network Preying on UK Gamblers Via GamStop Loopholes

An investigation led by the Guardian alongside Investigate Europe has pulled back the curtain on a massive illegal online casino network; operators based in Curaçao under Santeda International previously leaned on support from Georgia's Upgaming AG, while unlicensed platforms like MyStake, Velobet, and Goldenbet drew in crowds of vulnerable UK gamblers sidestepping GamStop self-exclusion tools. Data from the probe reveals these sites racked up 2.3 million monthly visitors from the UK alone between November 2025 and January 2026, a figure that underscores just how deeply entrenched this operation became despite regulatory efforts. Observers note the network's design exploited gaps in enforcement, allowing easy access through affiliates who openly promoted ways around GamStop, the UK's national self-exclusion scheme meant to shield problem gamblers.

What's interesting here is the sheer scale; these platforms didn't just pop up overnight but formed a web of interconnected sites sharing infrastructure, payment systems, and marketing tactics tailored to lure British players frustrated with licensed operators' restrictions. Researchers from the collaborative investigation tracked how Santeda International, licensed only in Curaçao—a jurisdiction known for lax oversight—funneled traffic through mirrors and affiliates, evading UK domain blocks that the Gambling Commission had put in place. And while the core operation hummed along, UK visitors poured in, chasing slots, tables, and bets without the protections afforded by white-listed sites.

Santeda International stands at the heart of this empire, a Curaçao-registered entity that investigators linked directly to the unlicensed trio of MyStake, Velobet, and Goldenbet; previously, Upgaming AG from Georgia provided the tech backbone, including software for games and player management, before distancing itself amid scrutiny. Figures show these sites mirrored each other in design and offerings—slots with high volatility, live dealer tables, sportsbooks—all optimized for mobile play and quick deposits via crypto or e-wallets that bypassed stricter UK financial checks. Take one case highlighted in the report: a UK gambler lost £23,000 in a single binge on MyStake, a platform that ignored GamStop registrations and kept the doors wide open.

But here's the thing; affiliates played a starring role, with influencers and sites earning commissions by hyping "GamStop-free" zones, directing traffic straight to these operators through SEO tricks and paid ads on social media. Experts tracking the network observed how domains shifted rapidly—blocked one day, reappearing under new URLs the next—rendering the UK's Payment Blocking Regulations more symbolic than effective. Data indicates over 100 affiliate partnerships funneled players, many of whom had self-excluded via GamStop precisely to avoid such temptations.

November 2025 through January 2026 marked a peak for this influx, as 2.3 million UK visits per month lit up analytics from the sites; that's not just casual browsers but active depositors wagering real money on everything from progressive jackpots to roulette wheels unlicensed in the UK. Studies tied to the investigation found patterns of fraud too, including bonus abuse schemes where players colluded to exploit wagering requirements, while others fell victim to rigged odds or withdrawal delays that drained accounts dry. One tragic outcome surfaced in January 2026: a suicide linked explicitly to gambling losses on one of these platforms, a stark reminder of the harms when safeguards crumble.

People who've analyzed GamStop data point out that around 200,000 UK users had enrolled by late 2025, yet this network siphoned off those seeking quick fixes; Velobet, for instance, boasted football betting during the holiday season, pulling in punters who couldn't access Bet365 or similar due to self-exclusion. Goldenbet targeted slot enthusiasts with free spin lures that hooked players into deeper spending, all while the sites flaunted VIP programs promising cashback and exclusive bonuses unavailable on regulated turf.

The UK Gambling Commission, armed with £26 million in funding for enforcement, has struggled to stem the tide; despite powers to block payment processors adn domains, the network persisted by rotating IPs and leaning on offshore hosting. Labour MP Alex Ballinger, chair of the Gambling Related Harm All-Party Parliamentary Group, called for tougher laws in direct response to this exposé, arguing that current tools fall short against agile operators like Santeda. Reports from April 2026 highlight how the Commission's whitelist—limiting ads to licensed sites—proved porous, as affiliates skirted rules with subtle messaging like "play anywhere, anytime."

Turns out enforcement hit roadblocks early; domain blocks by ISPs covered major URLs but missed the mirrors proliferating weekly, and while crypto payments complicated tracing, investigators noted Upgaming AG's pivot away from Santeda coincided with rising heat from European watchdogs. Ballinger's push echoes broader calls for a levy on offshore sites or mandatory GamStop integration worldwide, though implementation lags amid these revelations.

Affiliates form the connective tissue here, with networks promoting these casinos through review sites, YouTube breakdowns, and Telegram channels; commissions ran 30-50% on losses, incentivizing aggressive GamStop-bypass tutorials that researchers documented in droves. One study revealed over 50 UK-focused affiliates driving 40% of traffic to MyStake alone, using phrases like "escape self-exclusion" to reel in the desperate. And although the Gambling Commission ramped up warnings, accessibility remained child's play— a simple VPN or mirror link sufficed, keeping the 2.3 million monthly tally climbing.

Observers who've monitored similar setups know the pattern; Curaçao licenses offer minimal player protections, no ties to UK dispute resolution, leading to complaints piling up unanswered. Velobet's sports focus during Premier League matches, paired with Goldenbet's slot marathons, created a one-stop evasion hub that regulators chased but rarely caught.

As of April 2026, the story continues unfolding; the Guardian's probe prompted parliamentary questions and Commission reviews, yet sites persist under fresh domains, underscoring enforcement gaps. Data suggests visitor numbers dipped slightly post-exposure but rebounded via affiliates, while cases like the £23,000 loss and January suicide fuel demands for overhaul. Experts tracking offshore gaming note Curaçao's role in similar networks, with Upgaming AG's exit hinting at potential shifts to newer backers.

Now, with Ballinger advocating for GamStop mandates on all UK-facing sites, the ball's in the regulators' court; until then, vulnerable players navigate a landscape where self-exclusion means little against determined operators.

This investigation lays bare a network that thrived on UK vulnerabilities, amassing millions of visits while inflicting real-world damage from fraud to fatalities; Santeda International's Curaçao base, bolstered by past Upgaming ties and affiliate armies, exposed limits in the Gambling Commission's arsenal despite substantial funding. As calls for reform grow louder—led by figures like Alex Ballinger—the path forward hinges on closing loopholes, enforcing blocks more rigorously, and curbing affiliate promotions that keep GamStop bypasses front and center. Figures from the 2.3 million visits serve as a wake-up metric, pushing stakeholders toward measures that match the operators' cunning.
