Yes, but I wouldn't underestimate their foreign propaganda. It's very obvious in some countries, for example mine (Bulgaria), where trolls affiliated with Russia regularly flood articles with anti-EU and anti-US comments.
I feel like I hear this comment every time the subject comes up. Are there people with stories about anti-Russian British sockpuppets on Vk or whatever? I never hear that story, but maybe it's because I don't spend time on Runet.
