According to Brzoska, Meta had "for years" had the technology, money and data to detect fraud, yet scams remained widespread on its platforms.
"Why? Because it simply pays off," he told a press briefing on Monday.
According to the Instrat Foundation, a Warsaw-based think tank, scams generate around PLN 760 million (USD 200 million) a year for Meta's platforms in Poland alone, Brzoska wrote on X.
He wants tech companies to verify who buys and pays for an advert before a campaign starts, using anti-money-laundering (AML) and know-your-customer (KYC) standards of the kind applied by banks.
If a fraudulent advert is published anyway, the platform should be fined 150 percent of the revenue it earned from it, he said.
He also proposed that part of any fines go into a fund for victims of online fraud.
The proposals come from a campaign called "150 percent," which Brzoska launched in late August.
Its report, based on an AI tool called ScamWatch, analysed more than 2 million adverts in Meta's Polish ad library between September 9 and 20.
It rated 16.5 percent as "suspicious" and 1.6 percent – about 28,000 paid content items – as posing a "very high risk" of being illegal.
These included ads impersonating companies and institutions, investment scams, attempts to extract personal data, unlicensed health claims and promotion of illegal gambling.
Brzoska said his team had evidence that Meta was breaching the EU's Digital Services Act (DSA), which makes online platforms responsible for content posted on their services.
Polish Deputy Digital Affairs Minister Dariusz Standerski said the ministry was analysing the proposals and would work to implement "any additional solution" that effectively cuts online scams.
Poland has yet to fully adopt the DSA.
President Karol Nawrocki vetoed a bill implementing the act in January, arguing it could limit free speech.
A narrower bill, which would make the head of the telecoms regulator the national enforcer of the rules, is awaiting the president’s signature.
