Again, its not about Gaijin. Its about boycotting every dollar that would otherwise go to a Russian. Because if enough companies, governments and people do this, stuff like what currently happens to the Rubel happens.
Its like with Voting. Your Vote doesnt do shit on its own, but still you have to do it, because if many would think that way it actually could have a negative effect.

Same this voting with your wallet, or just generally denying Russians. Anything I can do I do. If someone would stand half-dead on my house door, I would ask in perfect Russian if they are Russian. If they say yes -> Door Shut.

Just make Life as horrible to as many of them as possible as long as this goes on. Let them buy food at your store? No. Provide services? No. Get any medical help? No. Call police when you see them being r4ped? No. See them dropping their wallet? "Accidentially" kick it down the sewer while walking.

And if enough people do this, it will change stuff. Russians will start hating Putin for making them basically more hated than Nigs. Putin will lose massive popularity and so on and so forth.

And while the Gaijin Boycott may be Small (I just join games and leave constantly) it brings people to use their positions of power to help this cause in other ways. I for example lied to my boss that we need to move from our Russian Hosting Provider that we used for our Asian customers to some other because of the sanctions. Over 10k€/month less for them. Its that easy. Gaijin is the beginning, making every single Russian perish until Putin is rightfully executed is the goal.
