Vast Illegal Casino Network Sidesteps GamStop, Draws Millions of UK Visitors Amid Rising Harms

A massive illegal online casino network, orchestrated by Santeda International from its base in Curaçao, has quietly ensnared vulnerable UK gamblers by deftly bypassing the nation's GamStop self-exclusion scheme; this operation, which flourished through November 2025 to January 2026, pulled in 2.3 million monthly visitors from the UK alone, according to figures revealed in a recent Guardian investigation.

Brands like MyStake, Velobet, and Goldenbet sat at the heart of this web, offering slots, table games, and sports betting without the oversight demanded by UK licensing rules; operators lured players with aggressive promotions, fast payouts, and an illusion of accessibility, even for those who'd opted into GamStop to curb their habits.

What's interesting here lies in the network's scale—operators ran over 20 sites simultaneously, each mirroring the others in design and odds, while sharing backend tech that funneled data and deposits seamlessly across borders.

Santeda International, registered in Curaçao—a hub for offshore gambling outfits—served as the linchpin, with ties tracing back to Georgian businessmen Tornike Tvauri, Alexander Makashvili, and Mikheil Merebashvili; these figures, previously flagged in European probes, controlled the operation through a Swiss-based software provider called Upgaming AG, which supplied the platforms until severing ties in March 2026 amid mounting scrutiny.

Upgaming AG's role proved pivotal; the company delivered customizable casino software that powered seamless user experiences, complete with live dealers and progressive jackpots, yet without the geoblocking required to exclude self-excluded Brits, allowing GamStop registrants to deposit freely and chase losses unchecked.

And while Upgaming distanced itself last month, evidence suggests the network persisted; domain records and payment trails, unearthed by investigators, show Santeda's servers rerouting traffic through mirrors in Cyprus and Georgia, keeping the sites alive even as regulators closed in during early April 2026.

Take one affiliate marketer who promoted Velobet heavily on UK forums; this individual, now under investigation, reportedly earned commissions on deposits from problem gamblers, highlighting how the ecosystem thrived on referrals bypassing official channels.

Traffic data paints a stark picture; from November 2025 through January 2026, the network clocked those 2.3 million UK visits per month, a surge fueled by SEO tricks, social media ads disguised as tips, and emails promising "GamStop-free fun," drawing in players frustrated by licensed sites' limits.

But here's the thing—beyond the numbers, real harm unfolded; reports link the sites to widespread financial distress, with one tragic case in January 2026 where a gambler, excluded via GamStop yet active on Goldenbet, took his own life after spiraling debts, as detailed in coroner's findings cited by the Guardian.

Fraud added another layer; users encountered rigged slots that rarely paid out advertised jackpots, chargeback scams where withdrawals vanished, and bonus terms twisted to lock funds indefinitely; one study of player complaints, aggregated by gambling watchdogs, revealed over 500 UK cases tied to MyStake alone in that period, many involving sums exceeding £10,000.

Observers note how these platforms preyed on vulnerability; they accepted deposits via UK bank cards and e-wallets, ignoring self-exclusion signals, which left players like a Manchester factory worker—who lost £45,000 in weeks—facing bankruptcy without recourse, since offshore laws shielded operators from British courts.

The UK Gambling Commission (UKGC) stepped up in April 2026, announcing plans to pursue affiliates profiting from the network; spokespeople confirmed blacklisting of payment processors linked to Santeda, while urging banks to flag suspicious transactions to sites like Velobet.

Yet the real push centers on new powers; the Commission seeks authority to block domains at the ISP level, mirroring measures against illegal betting rings, a move backed by MPs who heard testimony on GamStop's loopholes during parliamentary sessions last month.

Data from the November 2025 budget underscores the stakes; estimates there pegged gambling-related harms at £1.3 billion annually for the UK economy, with offshore sites contributing a growing slice as licensed operators faced stricter affordability checks.

So far, actions have yielded results; UKGC enforcers shuttered several mirrors post-Guardian exposé, and Curaçao authorities, under pressure from Brussels, revoked Santeda's sub-license—though experts caution that without domain blocks, savvy players can still access via VPNs.

There's this case of a London-based streamer who, despite warnings, continued shilling MyStake for crypto kickbacks; regulators now target such influencers, freezing ad revenues and demanding repayment of illicit earnings.

This network fits a larger trend; researchers tracking iGaming flows have observed similar Curaçao outfits spiking UK traffic by 40% year-over-year, often using Georgian or Eastern European proxies to dodge enforcement, while software firms like Upgaming provide plausible deniability until scandals erupt.

Figures reveal the bypass mechanics clearly; GamStop shares exclusion data with UKGC-licensed firms only, leaving offshore operators free to onboard anyone with a card, a gap that's ballooned since self-exclusion launched in 2018.

And while brands rebranded swiftly—Goldenbet spawning clones like GoldRushBet—their footprints linger in blockchain ledgers, where Ethereum wallets tied to Tvauri funneled winnings offshore, evading AML checks that trip up compliant sites.

People who've studied this know the rubber meets the road in enforcement; one watchdog group mapped 150+ non-GamStop sites active in March 2026, with Santeda's cluster leading by volume, prompting calls for an EU-wide blacklist to starve them of liquidity.

As April 2026 unfolds, the UKGC's affiliate hunts intensify, with fines looming for marketers who've pocketed six figures from referrals; meanwhile, lawmakers debate the Gambling Act white paper, eyeing mandatory checks on all inbound traffic regardless of licensing.

Turns out, player education plays a role too; campaigns now flood socials with tools to spot offshore red flags—like missing UKGC badges or Curaçao seals—urging deposits only where self-exclusion holds sway.

It's noteworthy that severance by Upgaming signals cracks; other providers watch closely, as reputational hits could cascade, forcing even lax jurisdictions to tighten sub-license scrutiny.

Yet challenges persist; with VPNs and crypto muddying trails, full eradication demands global coordination, something Curaçao pledged in talks last week, though skeptics await proof amid ongoing raids on Tvauri-linked offices in Tbilisi.

The Santeda saga underscores vulnerabilities in the UK's gambling shield; by drawing 2.3 million visitors while dodging GamStop, this network inflicted tangible damage—from fraud and debts to a preventable suicide—prompting swift regulator moves in April 2026.

Data indicates progress through affiliate pursuits and domain block bids, but experts who've tracked these operations emphasize sustained vigilance; as offshore players adapt, bolstering GamStop's reach emerges as key to protecting those at risk, ensuring self-exclusion means what it promises across borders and bytes alike.

In the end, the writing's on the wall for unchecked networks; with harms quantified and spotlights glaring, the push for airtight reforms gains momentum, aiming to reclaim control from shadows cast by Curaçao and beyond.
