Guardian Investigation Uncovers Illegal Casino Network Targeting UK's Self-Excluded Gamblers

A joint investigation by The Guardian and Investigate Europe has revealed a sprawling network of at least eight illegal online casinos operating from Curaçao under the umbrella of Santeda International; these platforms lack any license from the UK Gambling Commission, yet they've aggressively targeted vulnerable UK gamblers, particularly those who've self-excluded through GamStop, by leveraging affiliates who promote so-called "not on GamStop" sites. What's interesting is how this operation sidesteps UK protections designed to shield players from their own impulses, drawing in crowds who thought they'd locked themselves out of gambling altogether.

Researchers from the investigative teams dug deep into company records, software connections, and traffic data, uncovering ties that bind these sites together; Santeda International emerges as the central player, basing its unlicensed activities in Curaçao, a jurisdiction known for lax oversight on such matters, while funneling UK players into a web of high-stakes games. And here's the kicker: affiliates blast out promotions across social media and forums, dangling bonuses and easy wins to those desperately seeking loopholes around self-exclusion.

At the heart of this network sit prominent brands like MyStake, Velobet, Goldenbet, and Rolletto; these sites share more than just flashy interfaces and promises of big payouts, as data shows they rely on the same backend software from Upgaming, a provider linked directly to Georgian businessmen such as Tornike Tvauri. Experts who've traced the digital footprints note how Upgaming's tech stack powers multiple domains, creating a seamless operation that evades single-point shutdowns; Georgian nationals, including Tvauri, hold key roles in entities connected to Santeda, with corporate registries in Curaçao listing them as directors or shareholders.

Take MyStake, for instance, where UK visitors flood in despite clear warnings on licensed sites about GamStop compliance; Velobet follows suit, offering sports betting alongside slots that mirror those on regulated platforms, while Goldenbet and Rolletto amp up the appeal with crypto deposits and rapid withdrawals designed to hook players fast. Observers point out that these connections aren't coincidental, since shared payment processors and identical game libraries scream coordinated effort, all orchestrated from afar to dodge UK enforcers.

Figures reveal the scale of the influx: between November 2025 and January 2026, these eight sites averaged 2.3 million unique UK visitors each month, a number that underscores how effectively affiliates pierce through GamStop's barriers; self-excluded players, who've opted into a central registry to block access across licensed operators, find themselves welcomed with open arms on these offshore alternatives. Data from traffic analytics tools confirms the trend, showing spikes during evenings and weekends when vulnerability peaks for those battling addiction.

But here's where it gets interesting: GamStop, launched to give players control, covers only UK-licensed sites, leaving a glaring loophole that Santeda's network exploits ruthlessly; affiliates rake in commissions by steering traffic, often using coded language like "GamStop-free zones" in ads that pop up on search engines and Telegram channels. Those who've studied the patterns report that UK IP addresses dominate visitor logs, with deposit methods tailored for British users, from Visa cards to e-wallets popular in the region.

The human cost hits hard, as financial losses mount for players who believed they'd escaped temptation, only to dive back in through these unlicensed doors; reports detail cases of depleted savings, mounting debts, and fractured families, with the Gambling Commission's own data indicating that unlicensed sites amplify risks by skipping age verification and responsible gambling tools. A stark example emerged in January 2026, when a coroner's inquest linked a suicide directly to unlicensed gambling sites; the deceased had self-excluded via GamStop but turned to offshore platforms, spiraling into losses that coroners ruled as a contributing factor.

Studies from addiction researchers highlight how such networks prey on the desperate, offering credit lines and bonuses that licensed sites can't match, while lacking deposit limits or reality checks; one analysis found average session times stretching hours longer on these platforms, fueling addiction cycles that GamStop aims to break. And yet, the pull proves irresistible for thousands, as visitor numbers attest.

UK parliamentarians have sounded the alarm, with Labour MP Alex Ballinger and Conservative Iain Duncan Smith leading calls for the Gambling Commission to wield new powers; these include blocking domains and IP addresses tied to illegal operators, tools unlocked by recent legislation to combat offshore incursions. Ballinger, chair of a cross-party group on gambling harms, described the network as a "clear and present danger" in April 2026 statements, urging swift enforcement.

Duncan Smith echoed the sentiment, pointing to the £26 million funding boost announced in the November 2026 budget, cash meant to supercharge the Commission's tech defenses and investigative muscle; that money, part of a broader push to modernize oversight, equips regulators with AI-driven monitoring to spot and shut down rogue traffic in real time. MPs argue the time for half-measures has passed, especially as self-exclusion sign-ups hit record highs amid rising problem gambling rates.

The Gambling Commission now holds enhanced authority under the updated Gambling Act, allowing it to issue blocking orders to ISPs and payment providers, a direct response to networks like Santeda's; past efforts snagged individual sites, but this probe exposes the interconnected web, prompting questions about whether fragmented takedowns suffice. Experts monitoring the space predict a cat-and-mouse game, where operators mirror domains or shift servers, yet the funding infusion promises more proactive hunts using shared intelligence from Europe.

Collaborations with international bodies, including Curaçao's gaming authority, could tighten the noose, although enforcement there remains spotty; UK players, meanwhile, face stark warnings from charities like GambleAware, which track how "not on GamStop" lures lead straight to harm. As of April 2026, the Commission has signaled investigations into named sites, with potential fines or asset freezes on the horizon for affiliates profiting from UK misery.

This Guardian-led exposé lays bare a sophisticated evasion tactic that's funneled millions of vulnerable UK visits into unlicensed casinos, linking Curaçao operations to Georgian backers via Upgaming tech; with 2.3 million monthly uniques, documented harms including a suicide inquest, and MPs pushing for blocks backed by £26 million, the pressure mounts on regulators to act decisively. Observers watch closely as new powers test against offshore resilience, while self-excluded players navigate a landscape where GamStop's shield falters; the reality is that closing these loopholes demands not just tech, but cross-border grit, ensuring protections hold firm against networks that thrive in the shadows.
