Guardian and Investigate Europe Uncover Offshore Casino Network Targeting UK GamStop Users

The Investigation That Lifted the Lid

A joint probe by The Guardian and Investigate Europe has spotlighted a sprawling network of at least eight unlicensed online casinos, including prominent names like MyStake, Velobet, and Goldenbet; these platforms, operated by Santeda International from offshore hubs such as Curaçao, actively court UK gamblers who have self-excluded through GamStop, the UK's national self-exclusion scheme, via aggressive affiliate marketing tactics that slip past regulatory barriers.

What's interesting here is how these sites, linked through a web of companies including Upgaming AG tied to Georgian businessmen, manage to thrive despite clear violations of UK Gambling Commission (UKGC) rules on addict protection measures and anti-money laundering (AML) safeguards; experts who've tracked similar operations note that such networks often exploit jurisdictional gaps, registering in places like Curaçao where oversight remains lax compared to the stringent standards enforced in Britain.

And while UK-licensed operators must adhere to GamStop integration—blocking self-excluded players from their sites—these offshore alternatives advertise directly to that vulnerable group, promising unrestricted access and bonuses that lure players back into the fold; turns out, this isn't just a loophole, but a deliberate strategy, as affiliates promote the casinos on social media, forums, and email lists tailored to those who've hit the self-exclusion button.

Mapping the Network's Operations

Santeda International N.V., the Cyprus-registered entity behind much of this, holds a Curaçao eGaming license that covers its portfolio of brands; researchers examining company filings and domain records discovered shared infrastructure, payment processors, and even identical slot games across MyStake, Velobet, Goldenbet, and others like Immerion, But while Curaçao licensing allows global reach, it falls short of UKGC requirements for player protection—think mandatory reality checks, deposit limits, and seamless self-exclusion syncing—which these sites simply ignore.

Upgaming AG, a Swiss firm connected to Georgian entrepreneurs Shalva Uchaneishvili and Levan Kvirkvelia, emerges as a key player; according to corporate registries, it supplies the software backbone for these casinos, facilitating everything from game integration to affiliate tracking systems that reward promoters for driving UK traffic, even from self-excluded individuals.

Here's where it gets interesting: data from affiliate networks reveals commissions as high as 50% of net revenue from referred players, incentivizing marketers to target high-risk groups; one affiliate dashboard screenshot shared in the investigation showed UK-focused campaigns explicitly mentioning "GamStop-free" zones, a phrase that underscores the deliberate circumvention of UK safeguards.

Observers note that these platforms process deposits via cryptocurrencies and e-wallets popular in the UK, further complicating AML efforts since transactions zip across borders without the scrutiny UK banks apply to licensed sites; and although Curaçao regulators claim oversight, enforcement remains spotty, with few documented cases of license revocations for targeting restricted markets like Britain.

Evading Regulations and the Human Toll

The UKGC mandates that operators protect problem gamblers through tools like GamStop, yet these offshore sites boast no such integrations; instead, they flaunt unlimited deposits, high-stakes tables, and slots with RTPs (return to player percentages) that mirror licensed games but without the protective nets, leading to unchecked play sessions that spiral out of control.

But here's the thing: the real damage shows in personal stories unearthed by the probe; take Sarah, a 38-year-old from Manchester, who self-excluded via GamStop in 2025 after mounting losses, only to find MyStake ads in her inbox weeks later—within months, she lost £23,000 chasing withdrawals that never materialized, her account frozen amid bonus disputes that unlicensed sites often wield as weapons.

And tragedy strikes harder: in January 2026, a 42-year-old man from London took his own life after accruing debts on Velobet, despite his GamStop registration; coroner's reports cited gambling addiction as a contributing factor, with family members pointing to targeted emails from affiliates that promised "easy wins" and ignored his exclusion status, highlighting how these networks exacerbate vulnerabilities.

Figures from the investigation paint a broader picture: thousands of UK players engage these sites monthly, with deposit volumes in the millions, per affiliate payout logs; studies by gambling harm researchers indicate self-excluders face triple the relapse risk when offshore options remain accessible, a pattern these casinos exploit ruthlessly.

Affiliate Marketing: The Hidden Engine

Affiliates form the frontline of this operation, with networks like Scaleo and Affilka powering referrals; one marketer interviewed anonymously admitted earning £10,000 monthly by promoting "non-GamStop" casinos to UK audiences on Telegram channels and Reddit threads, where desperate players seek alternatives.

Turns out, these promoters often use SEO tricks—keywords like "best casinos not on GamStop"—to dominate search results, drawing in those frustrated by UK restrictions; and while the UKGC has blacklisted some affiliates, the offshore nexus makes enforcement tricky, as servers hide behind VPNs and proxies.

People who've studied affiliate ecosystems point out that commissions scale with player lifetime value, encouraging long-term engagement over quick wins; this model sustains the network, funneling revenue back to Santeda despite occasional payment processor crackdowns.

Political Pushback and Calls for Action

UK lawmakers have seized on the exposé, with Labour MP Alex Ballinger labeling it "a scandal that demands urgent reform," pushing for expanded UKGC powers to block offshore sites at the ISP level; Conservative heavyweight Iain Duncan Smith echoed this, urging sanctions on Curaçao licenses that enable UK targeting and tougher penalties for affiliates operating domestically.

Now, as of April 2026, parliamentary debates heat up ahead of the Gambling Act review; data from similar European probes shows countries like Sweden and Germany have curbed such networks through payment blocking and affiliate bans, measures Ballinger and others advocate for Britain.

Yet challenges persist: the UKGC reports pursuing over 200 unlicensed operators in 2025, fining affiliates £5 million, but offshore resilience—bolstered by crypto—means new brands pop up as fast as others fall; experts observe that international cooperation, perhaps via EU gambling frameworks post-Brexit, could tighten the noose.

One case study from the Netherlands illustrates potential: after a 2024 crackdown, affiliate revenues from Dutch players dropped 70%, per industry trackers, suggesting what coordinated action might achieve here.

Broader Implications for UK Gambling Landscape

This network exemplifies a growing black market, where unlicensed sites capture 15-20% of UK online spend according to UKGC estimates; while licensed operators invest in safer gambling—£200 million annually on tools—these rivals undercut with lax rules, eroding trust and revenue that funds protections.

And it's not just individuals: the Exchequer loses billions in untaxed winnings, with MPs citing £1.5 billion annual leakage to offshore havens; researchers warn that without barriers like GamStop expansion to social media ads, harm levels—already at 500,000 problem gamblers—could climb further.

So, as the Guardian probe ripples through Westminster, operators like Santeda watch closely; past patterns show they pivot to new domains or jurisdictions, but heightened scrutiny might finally clip their wings.

Conclusion

The Guardian and Investigate Europe investigation lays bare a calculated assault on UK player protections, with Santeda International's casinos like MyStake and Velobet luring GamStop users through affiliates, evading AML and harm-minimization rules from Curaçao bases linked to Upgaming AG; stark cases—a £23,000 loss, a January 2026 suicide—underscore the stakes, spurring MPs like Ballinger and Duncan Smith to demand ISP blocks, affiliate crackdowns, and global pacts.

What's significant is the momentum building in April 2026: with UKGC reviews underway, this exposé could catalyze changes that seal offshore loopholes, safeguarding self-excluders and restoring regulatory muscle; until then, those who've self-excluded remain prime targets, a reality the gambling world can't ignore.
