Why not boycott mass media or press instead then? There are little independent news channels or reporters, majority belongs to someone and show truth profitable for only one part of party. Same as crypto influencers, that just get paid to say what is scripted.

Ukraine wont surrender, Russia wont stop until they reach their "unclear goal of this war" (otherwise other countries will jump on Russia like hyenas on dying lion and tear it apart). Make more sanctions against - everyone suffer from sanctions now. Russia suffers now, other countries will suffer later. Boycotting Russian gambling platforms ? I dont believe it will help, as foreigners dont gamble there much.
