Russia doesn't control X moderation policies or algorithms. These accounts have gained the purchase they have because Silicon Valley and Elon Musk specifically now see it as advantageous to sow racial animus and division, and to scapegoat migrants for domestic problems which are in fact caused by elite looting. This is being done to strengthen the status quo regime, not undermine it.
I just pointed to evidence this was happening several years before Elon had anything to do with Twitter takeover, all the way back when Obama was still in office.
One of the central points of the Mueller report is that they were organized and operated at a large scale, running major social media accounts and were infiltrating various fringe groups such as the Tea Party and BLM.
Though it's worth noting this was happening under Prigozhin's lead, and since he's fallen out of a window now, it's unclear what's become of his troll factories.
You could pilot a 747 through the range that encompasses what one might mean by "a large scale." None of the Mueller findings really showed anything likely to have had a substantial impact on popular discourse or voting, or anything within even 2, probably 3 orders of magnitude of the algorithmic reach of the modern day Xitter bluecheck flying monkeys. These accounts couldn't even get bluechecks back then!
