Payment Blocking

Payment blocking has become the enforcement tool of choice in jurisdictions that have concluded site blocking does not work. A blocked domain is replaced within hours by a mirror; a blocked payment relationship is far harder to reconstruct, because it requires an acquirer willing to take the risk and a route that survives the compliance obligations placed on regulated financial institutions.

Its effectiveness depends on the payment landscape. Where a market runs on a small number of domestic rails, Pix in Brazil, iDEAL in the Netherlands, Interac in Canada, blocking bites hard. Where consumers can reach international cards, e-wallets or crypto, leakage is substantial. That is why modern statutes drafted with this in mind extend the obligation beyond banks to payment institutions, payment scheme operators and virtual asset service providers, and expressly reach transactions where the beneficiary or processor sits abroad. The counter-argument is proportionality: an obligation to monitor for gambling-related flows puts a policing function on private financial firms and creates false positives for legitimate businesses. It is nonetheless the direction of travel almost everywhere the black market is a policy concern.
