the attack on Azov POWs.

Russia 100% murdered them, and there is clear evidence of it from numerous sources. There was never any HIMARS strike on that building. Numerous eyewitness accounts state that Russia moved all their "Azov" inmates to a building rigged with incendiaries then set them off to murder the POWs. Russian video of the aftermath is 100% consistent with setting the place on fire, as opposed to a HIMARS strike which would have blown a small hole in the roof and not torched the whole place. Remember "potholes"? HIMARS warheads are pretty small.

Nord Stream 2 and all that, when you were absolutely sure that it was an inside job when Russia can just shut down the pipeline.

No, I was not "absolutely sure" but I think it is more likely that Russia did it to themselves. There are a number of reasons why they would do it, such as to play the victim, to justify escalation, for Putin to shore up internal support, etc. The alternative explanation is that the US/UK did it, which I simply don't believe because those governments don't operate that way, and if they did it, it would cause a rift between those governments and Germany, which might have been the Russian goal. Since Germany has not gotten mad about it, that shows that German intelligence thinks it was the Russians, too.

Russia, as a state, is run as a scheming KGB entity since Putin is dictator and his whole background is KGB. They do weird and shady shit all the time, far moreso than other countries, even China. They also don't fool anyone, but the Russians don't even care, and keep doing it anyway. Probably because it still works for domestic consumption.

If an FSB contractor has nothing better to do than argue on a forum with 30 people, then I can imagine why things went not as planned.

Investigative stories of Russian bot farms and contractor farms showed that they were more for quantity than quality. It was more about getting your quota of comments and posts out than actually trying to farm maximum "karma" in reddit terms. Democrat propaganda on reddit for example is way more sophisticated, though of course they are working with an extremely compliant user base that is easily manipulated.
