Slightly more complicated because a ton of the abuse comes from IPs located western countries, explicitly to evade fraud and abuse detection. Now you can go after the western owners of those systems (and all the big ones do have have large abuse teams to handle reports) but enforcement has a much higher latency. To be effective you would need a much more aggressive system. Stronger KYC. Changes in laws to allow for less due-process and more "guilty by default" type systems that you then need to prove innocence to rebut.
