“Astroturfers” may be a more accurate term. Especially in regards to Israel and Ukraine. There’s videos you can look up where they train Zionists to astroturf forums and strategically edit Wikipedia. The US Air Force has a massive astroturf farm at Eglin Air Force base pushing a lot of this, too.

Whether these commenters are professional astroturfers, or just repeating what they’ve heard from one, I don’t believe it a meaningful distinction to make.
