oh, there were so many of those during the first months of the war! most websites had simply put up a "I support the current thing" banner, but some really went out of the way. it was actually amusing to click a link to some fuckass blog that probably gets 5 visitors a day and get greeted with "NO RUSSIANS ALLOWED". I think it's safe to say by now that those measures weren't enough to incite a revolution or trigger an economic collapse, but hey, if it made those people feel like they were helping, who am I to judge?
sometimes I wonder if they did the same thing during Israel's carpet bombing of Palestinian civilians, or when America killed more children in a single strike than Russia does in a year of its genocidal all-out war. probably not, it's different after all.
