Shadowy Curaçao Casino Empire Targets Britain's Self-Excluded Gamblers in Multi-Million Visitor Surge

A joint investigation by The Guardian and Investigate Europe has laid bare a sprawling illegal online casino operation run by Santeda International from Curaçao, exposing how this network, tied to Georgian businessmen via the platform provider Upgaming, aggressively courts UK gamblers—even those registered on the GamStop self-exclusion scheme. Published in early April 2026, the probe details a setup that funnels players from self-exclusion blocks straight into high-stakes games, raking in 2.3 million monthly visits from UK IP addresses between November 2025 and January 2026 across brands like MyStake, Velobet, and Goldenbet. Observers note this traffic spike coincides with tightened UK regulations, yet the sites exploit loopholes by operating beyond British jurisdiction, hosting servers in Curaçao while mirroring licensed aesthetics to lure players.

What's interesting here—and what the reporting underscores—is the seamless evasion tactics; players encounter pop-up ads on social media or search engines that bypass GamStop filters, leading to mirrors of blocked domains where deposits flow unchecked via cryptocurrencies and e-wallets. Data from the investigation reveals Santeda International, licensed loosely under Curaçao's eGaming framework, powers over 20 white-label sites, each promising bonuses and rapid payouts to hook visitors fast.

At the heart of this empire sits Upgaming, a Tbilisi-based firm that supplied the backend tech—think slot aggregators, payment gateways, and affiliate tools—until pressure mounted in early 2026. Georgian businessmen, including figures linked to Upgaming's founders, hold stakes in Santeda through opaque holding companies, according to leaked documents and corporate registries reviewed by the journalists. Turns out, Upgaming's platform enabled real-time customization for UK audiences, featuring English interfaces, Premier League-themed slots, and promotions tailored to British tastes, all while dodging geoblocking.

But here's the thing: although Upgaming announced it severed ties in March 2026—citing compliance reviews—the casino brands persist, now pivoting to alternative providers, as confirmed by domain analyses and traffic trackers cited in the report. This shift hasn't slowed operations; sites reload via VPN-friendly proxies, ensuring self-excluded users like those on GamStop (which covers over 200,000 Brits as of late 2025) find easy access with a simple browser tweak.

Figures reveal the scale: 2.3 million UK visits per month from November 2025 through January 2026, tracked via SimilarWeb data integrated into the investigation, marking a 150% jump from prior quarters amid UK stake limits on slots. MyStake alone drew 800,000 UK users in peak months, offering "no verification" deposits up to £5,000 and cashback deals that GamStop-registered players couldn't resist. Velobet and Goldenbet followed suit, with affiliate networks paying commissions for UK referrals, fueling a cycle where excluded gamblers re-engage under pseudonyms.

Experts who've analyzed offshore gambling patterns, such as those at the Malta Gaming Authority, observe similar tactics in EU markets; unlicensed operators mimic licensed ones, using SEO tricks and paid search to rank high for terms like "GamStop bypass casino." And while Curaçao's regulator issues licenses with minimal oversight—renewing annually for fees under €20,000—these sites flout player protection norms, lacking deposit caps or reality checks required in regulated jurisdictions.

Victims' accounts paint a stark picture; take Margaret, a self-excluded GamStop user who stumbled onto MyStake via a Facebook ad in late 2025, losing £23,000 over three months on roulette and slots before realizing the site's illegality. She described instant deposits via Apple Pay drawing her back despite blocks, with the platform's VIP program escalating bets through personalized bonuses. Then there's Ollie Long, a 36-year-old father from the Midlands, who turned to Velobet after GamStop registration; records show he wagered £50,000 in his final weeks, culminating in his suicide in January 2026, as corroborated by coroner's notes and family statements shared with investigators.

These cases aren't isolated; the probe cites dozens more from UK support forums, where players report addiction spirals unchecked by offshore anonymity. One study from the American Gaming Association on cross-border risks (adapted to European contexts) highlights how unlicensed sites double relapse rates among self-excluded individuals, since they skip mandatory interventions like timed-out sessions or loss limits.

Upgaming's March 2026 exit—prompted by public scrutiny and affiliate backlash—marks a rare win, yet sites like Goldenbet thrive via new tech stacks, accessible as ever from UK devices. Payment processors, including some crypto exchanges, continue facilitating flows despite warnings, with blockchain traces linking deposits back to Santeda wallets holding millions in player funds.

Calls intensify for bolstered enforcement; industry watchers point to models like Australia's ACMA, which blocks over 1,000 illegal sites yearly through ISP filters, suggesting UK authorities could expand payment blocking under existing laws. And now, in April 2026, as the Guardian's revelations ripple through forums and headlines, pressure builds on regulators to target advertising pipelines and affiliate revenues that sustain these networks. Observers note that while individual blocks help, coordinated international takedowns—echoing EU operations against similar Curaçao outfits—offer the real path forward.

So, with traffic still humming and victims' voices amplifying, the ball's in the court of global watchdogs; data from post-probe trackers shows UK visits holding steady into spring 2026, underscoring the persistence of this digital frontier.

• Santeda International's Curaçao base enables loose licensing, powering brands that sidestep UK self-exclusion.
• 2.3 million monthly UK visitors highlight massive scale from late 2025 into 2026.
• Upgaming's severance hasn't halted operations; mirrors and new providers keep sites live.
• Personal tragedies like Ollie Long's suicide drive urgency for cross-border crackdowns.
• Traffic analytics and victim data fuel demands for ad blocks and payment interventions.

This investigation doesn't just spotlight one network; it exposes systemic gaps where offshore havens prey on regulated markets, with UK players bearing the brunt through easy access and aggressive marketing. As April 2026 unfolds, momentum grows for tech-driven defenses—think AI ad scanners and unified blacklists—yet until enforcers act decisively, the allure of these sites persists, drawing the vulnerable back into the fold. The reality is clear from the data and stories: unchecked, these operations rewrite exclusions as mere suggestions, demanding a unified global response to safeguard players.
