You were banned for rule 2, which is no political content. If we want to be charitable, it's possible that the mod considers talking about Russia's lack of technological progress to be a political statement. I can't imagine why somebody would be upset about that unless they had a hard-on for Russia, but surely that's not the case when the moderator also decided to extend the ban to such politically neutral communities as "Anarchist memes", "Socialism", and "The Right Can't Meme."
What's more insane is that you were banned from 20 communities in total, many of which aren't even related. Fucking power mods...
