"Active Measures" Was widely used by USSR back in the Cold War. WPC spreading conspiracy theory about US government is filled with blood thirsty Jewish capitalist in 50s, US was made HIV in Camp Detrick, Maryland, etc.
Mainly using disinformations (false stories to degrading the reputation of their adversaries) but also using "useful idiots". Back in 60s, using leftists peace protester (Yippies, BPP etc). Operation Zarathustra in Germany using anti-semitist to create chaos. Operation SIG using Arabs by spreading Protocols of Elders of Zion to spreading anti-semitism.
So basically, both on the right or left was used. Right now, mainly Russia subvert using the far-right (QAnon, Trumpist) But doesn't mean they are not using the left (BLM Movement and Bernie's leftists).
Yes, That's why people have to disconnect from both the left and right both are merely tools for the rich elite to manipulate the masses.
The left wing nonsense in Turkey is bad, but so is the totalarianism of the ak party islamists too.
