I present to you a real, still-active Russian troll account.

How do I know it's a troll account? Take a look at this: https://twitter.com/reshetz/status/1662112840554098688
Just like "There is no panic in Balakliya", there are occasionally moments when whole networks of these accounts tweet clearly scripted messages all at the same time which kind of gives the game away.

It's quite interesting to read, honestly. They have a decent pulse on what narratives are effective, but present it in such an consistently hamfisted and exaggerated form that it makes it just a bit too obvious if you're taking in more than one or two tweets. But it's twitter, most people don't do that.
We can argue about how effective this kind of stuff is, but that it's happening is pretty indisputable. You can say it's just a lie that everyone pretends to believe, but the documents leaked by Teixeira talk about this stuff in detail too.

This document for example says that the Russian Main Scientific Computing Research Center internally reports that only 1% of their social media bot accounts get shut down.
