I think that would be very difficult considering terms such as online and internet actually reside in land-based casino web sites. There would be no way to distinguish between them unless as a result of this law they chose to ban all information about any gambling game (such as blackjack, roulette, or keno), as well as all information about legal casinos (both online and land-based) throughout the world as well.
The only way to distinguish between them would be to have tens of millions of web sites constantly monitored by humans. That’s just not feasible.
Also, once banking restrictions are in place over time, such an action would be unnecessary. Furthermore, there appears to be no requirement in the bill that would force them to do this.
