Illegal Casinos Target UK Players via “Not on GamStop” Searches – Investigation
It’s estimated that as much as 9% of the UK’s online gambling market is now illegal (Source: iGaming). Even more worrying is that a growing network of offshore casino sites is actively targeting UK players, using ‘not on GamStop’ search terms and UK-focused messaging. Not only do these sites often promote themselves to self-excluded players, but they also operate without a UKGC licence

Illegal Casinos Target UK Players via “Not on GamStop” Searches
‘Not on GamStop’ Searches Driving Traffic
GamStop, the UK’s national self-exclusion scheme, means that not only does the ‘not on GamStop’ keyword directly target UK players, it more specifically targets players who have chosen to self-exclude.
Using the absence of GamStop as a key selling point flies in the face of protections put in place by the UK Gambling Commission, which had previously warned (Source: Gambling) that offshore operators may attempt to attract self-excluded players.
This is particularly concerning as these sites don’t operate under the rules of the UKGC, meaning they can offer larger bonuses with higher wagering requirements, as well as games that have not been independently tested for fairness.
UK-Focused Language and Features
Despite operating offshore, many of the platforms are tailored specifically to UK users. They have:
- GBP (£) as a default currency
- UK-focused sports markets such as Premier League football and horse racing
- English-language promotions referencing UK players
- Payment options commonly used by UK customers
Crypto Payments and Regulatory Gaps
Some of the platforms also promote cryptocurrency payments. Currently, UK Gambling Commission-licensed operators are not permitted to offer crypto gambling (Source: Sigman World). Crypto payments can make it:
- More difficult to trace transactions
- More difficult to resolve disputes
- Much easier to gamble anonymously
- Much easier to launder money
Offshore Licences Offer Limited Protection
Many of the operators are licensed in jurisdictions such as Anjouan or Curaçao, while some appear to operate without any recognised licence at all.
These licences do not provide the same level of consumer protection as regulation by the UK Gambling Commission. UK-licensed operators must comply with strict rules around affordability checks, responsible gambling tools, and dispute resolution - protections that may not apply to offshore sites.
This leaves the UK’s sports bettors and casino players in a difficult position if they come up against unfair terms, problems with payouts, or gambling-related harms.
