Black Market Crackdown: Romania Blocks Approximately 800 Illegal Gambling Sites
AI-GENERATEDThe Romanian regulator ONJN has issued a record update to its blacklist, targeting 800 unlicensed domains using new automated clone detection technology.
In Romania, the tide is turning against illegal online casinos as the national regulator takes unprecedented action. The National Office for Gambling (ONJN) has delivered a significant blow to unlicensed operators during its current mandate. On July 31, 2026, the Supervisory Committee announced the addition of approximately 800 illegal gambling sites to the national blacklist. This massive update underscores the pressure regulatory bodies face in protecting players from unregulated environments. It marks the largest single addition in the institution's history, far exceeding the previous record of 370 domains set earlier in the current leadership's term.
A key highlight of this enforcement action is the technological shift. For years, the blocking process was tedious and often ineffective, as operators would reappear under nearly identical web addresses just days after being banned. By utilizing a newly developed clone-site detection tool, the ONJN aims to break this cycle. The software identifies platforms that maintain the same underlying root and simply multiply through different domains. This is a direct counter-measure to the "cat-and-mouse" game played by offshore brands, including platforms like Polymarket, which have been flagged in recent periods.
Numbers and facts
The historical data provided by the ONJN illustrates the scale of the black market threat. Between its founding in 2013 and April 2025, the office blacklisted approximately 1,500 sites. Since the start of the current mandate in 2025, roughly 1,180 more have been added. This shows a dramatic acceleration in enforcement. Despite these successes, the agency faces significant internal constraints. Budget limitations mean they cannot easily expand staff, and attracting high-level IT specialists is difficult on a net monthly salary of about 6,000 lei. Automation has therefore become the only viable path for sustaining oversight.
“The black market is a systemic problem at European level. Over 70% of the European online gambling market consists of operators active on the black market.” - Vlad-Cristian Soare, President of the ONJN
Background
President Soare highlighted that Romania is implementing unique regulatory tools to stay ahead. The country is reportedly the only one in Europe to maintain a public registry of gaming devices, where machines feature QR codes that provide instant access to registration data and geolocation systems. For the online sector, the ONJN is moving toward deeper integration. By acquiring access to the servers of licensed operators, the volume of metadata becomes immense, requiring advanced digital tools and the use of the government’s private cloud for analysis. This transition from a reactive to a technology-based approach is intended to strengthen control capacity across the board.
Why it matters for German players
For players in Germany, the Romanian crackdown serves as a stark reminder of the risks associated with the black market. Germany operates under the Interstate Treaty on Gambling 2021, which provides a strict legal framework. Playing on sites without a GGL license means forgoing essential player protections. The Joint Gambling Authority of the States (GGL) maintains a whitelist of legal operators. These providers adhere to strict rules, including a 1 Euro per spin limit on slots and a cross-operator monthly deposit limit of 1,000 Euro monitored via the LUGAS system. While Romania fights mirror sites with domain blocks, Germany focuses on a centralized monitoring system to ensure player safety.
What it means for GGL-licensed casinos
For licensed German operators, aggressive enforcement in other EU states like Romania is a positive development for fair competition. Illegal operators avoid taxes and ignore responsible gaming mandates, creating an unlevel playing field. When regulators like the ONJN upgrade their technical capabilities, it increases the global pressure on shadow networks. GGL-licensed casinos must comply with high tax rates and advertising restrictions, but they benefit from legal certainty. The fight against clones and shadow platforms helps stabilize the legitimate industry across the European Union by rebuilding user trust in regulated digital offerings.
Frequently asked questions
How many websites did the ONJN blacklist?
On July 31, 2026, the regulator added approximately 800 illegal domains to the blacklist, marking a new record for the agency.
Why do blocked operators return so quickly?
Many illegal sites use "clones" or mirror domains with nearly identical URLs. When one is blocked, they simply launch the same content under a new address.
How does the authority detect these illegal sites?
The Romanian regulator now uses an automated clone detection tool that identifies the underlying technical root of a site regardless of its domain name.
What role does the European black market play according to ONJN?
President Vlad-Cristian Soare stated that over 70 percent of the European online gambling market is comprised of black market operators, calling it a systemic issue.
Are these sites dangerous for German players?
Yes, because illegal sites do not hold a GGL license and do not follow German player protection laws. German players should always consult the official whitelist to ensure they are protected by deposit limits and legal safeguards.
