A Guardian investigation published in April 2026 shines a spotlight on a sprawling network of unlicensed online casinos, operators like MyStake, Velobet, and Goldenbet sit at the heart of this operation, all run by Santeda International and tied to Georgian businessmen through the platform provider Upgaming, while these sites zero in on UK gamblers who've signed up for GamStop self-exclusion but seek ways around it via affiliate marketing channels.
Investigators mapped out how Santeda International, registered in Cyprus yet operating beyond easy regulatory reach, powers dozens of these casino brands; Georgian nationals linked via Upgaming handle the tech backbone, allowing seamless deployment of gambling platforms that dodge UK licensing requirements, and that's where affiliate sites come in, aggressively promoting these platforms to British players who've barred themselves from licensed operators through GamStop, the national self-exclusion scheme launched to protect problem gamblers.
But here's the thing: these affiliates don't just link casually; they target search terms like "non-GamStop casinos" and run ads on social media, forums, and even YouTube, drawing in users desperate to continue betting despite their own exclusion choices, and data from web traffic analysis (November 2025 - January 2026) reveals the scale, with an average of 2.3 million unique UK visitors hitting these sites each month over that three-month stretch.
GamStop, managed by the UK Gambling Commission, blocks registered users from 100% of licensed online gambling firms in Great Britain; yet these offshore sites, unlicensed and unregulated here, slip right through since they never signed on to the scheme, so self-excluded punters simply visit, deposit via crypto or e-wallets, and play slots, blackjack, or sports bets without any barrier, while affiliates earn commissions on every referral that leads to losses, fueling a cycle that experts have observed thriving in regulatory gray zones.
Turns out, one common tactic involves sites mimicking legitimate UK bookies with familiar branding or British-themed promotions; people who've analyzed the traffic patterns note spikes around major events like football matches or Cheltenham, where frustrated excluded gamblers hunt for alternatives, and that's not all, as payment processors sometimes overlap with those used by licensed firms, blurring lines further and complicating enforcement.
The investigation doesn't stop at operations; it digs into consequences, linking these casinos to widespread fraud like bonus abuse scams where players claim free spins then vanish, chargeback fraud draining operator accounts, and worse, severe financial ruin for UK customers who've lost homes or jobs, while estimates on gambling harm costs from related regulatory data paint a grim picture of billions in broader economic damage from illicit betting.
What's significant here involves at least one documented suicide tied to losses on these platforms; family members came forward detailing how a gambler, excluded via GamStop, found MyStake through an affiliate ad, racked up debts in weeks, and tragically ended his life, a case that underscores warnings from support groups like GamCare, which report surging helpline calls from players on non-GamStop sites facing addiction spirals.
And observers point out patterns: Velobet users complain of frozen withdrawals after big wins, Goldenbet accused of rigged slots via player forums, while Santeda-linked sites share identical backend software from Upgaming, enabling quick rebrands when heat builds, so enforcement becomes a game of whack-a-mole, with UK punters footing the bill through unrecoverable losses and emotional tolls.

In direct response to rising threats from such networks, the UK Chancellor announced an extra £26 million for the Gambling Commission during the November 2025 budget; this cash infusion aims to ramp up digital surveillance, international partnerships, and crackdowns on payment flows feeding unlicensed sites, while the Commission, already pursuing over 200 rogue operators annually, now eyes expanded teams for web scraping and AI-driven traffic monitoring.
So now, in April 2026 as the Guardian story breaks, regulators move faster; they've issued warnings to banks about suspicious crypto transactions linked to Santeda brands, collaborated with ISPs to disrupt affiliate ads, and pushed Google to demonetize non-GamStop promotions, yet challenges persist since Cyprus-based entities like Santeda enjoy lax oversight, and Georgian developers at Upgaming operate from Tbilisi hubs beyond easy extradition.
Affiliates form the front line; networks like those promoting MyStake rake in revenue shares up to 50% of player losses, with top UK earners reportedly clearing six figures monthly before platforms like these get blacklisted, but here's where it gets interesting: some affiliates operate from the UK itself, flouting Advertising Standards Authority rules by cloaking promotions as "reviews," prompting calls for stricter personal liability under the incoming Gambling Act reforms.
Take one case highlighted in the probe: a British affiliate site drew 100,000 monthly visitors with guides to "best GamStop bypasses," linking straight to Velobet; regulators shut it down temporarily, but mirrors popped up overnight, showing how resilient these channels remain despite efforts.
Figures reveal this network isn't isolated; Similarweb data captured those 2.3 million UK uniques per month from November 2025 through January 2026, equating to traffic rivaling major licensed sites like Bet365 on peak days, while researchers who've tracked offshore gambling note a 40% uptick in non-GamStop searches post-pandemic, driven by economic pressures and sports betting booms.
It's noteworthy that Santeda International powers over 20 brands beyond the named trio, all sharing Upgaming's white-label tech for rapid scaling; Georgian businessmen, often with prior experience in Russian-facing platforms, adapted swiftly to English markets, incorporating GBP deposits and Premier League odds to hook UK audiences seamlessly.
Yet enforcement data from the Gambling Commission shows progress; they've secured over £7 million in penalties from rogue sites last year alone, froze assets via civil recovery, and worked with the National Crime Agency on money laundering probes tied to casino proceeds, although full shutdowns remain elusive without host country cooperation.
Those who've studied victim reports list red flags: instant bonuses without ID checks, crypto-only payouts to skirt banks, and VIP programs pushing high-rollers into debt traps; GamStop users spotting these should report to the Commission hotline, which logged 15,000 complaints on unlicensed sites in 2025, up 25% year-on-year.
And support networks emphasize alternatives like peer counseling or debt advice from StepChange, where gambling debts from offshore operators topped £100 million in referrals last year, highlighting the human cost behind the numbers.
The Guardian's April 2026 exposé lays bare a sophisticated illegal casino web exploiting GamStop gaps, with Santeda International's brands like MyStake, Velobet, and Goldenbet drawing millions of UK visitors monthly amid fraud, financial devastation, and tragic losses; bolstered by £26 million in fresh funding, the Gambling Commission intensifies its fight, targeting affiliates, payments, and international ties, although the battle against such adaptable networks demands ongoing vigilance from regulators, tech firms, and punters alike, as illicit gambling's shadow lingers large over the UK's licensed landscape.
