This could be an effective approach but I guess even if we boycott the Russian gambling platforms, it still couldn't stop the war because aside from taxes from gambling, they still have lots of resources to support their current war. Innocent lives are already suffering from what is happening to their country but I believe that this too shall pass. The sad thing is, that this war could continuously take more lives.
Although it did not have any effect on Russia from the boycott of the gambling platform but it is only a small effort on our part not to support war on Ukrainian territory. I hope the war will end soon because many soldiers and civilians have fallen victim to the war without knowing when it will end.
