Modern political accusations of botting are more like a way to turn people with differing opinions into a non-person conspiracy, though. It's not as fun and silly as my old Markov bot.
I'd say that probably from about 2009 and certainly from the onset of the Trump candidacy, it would be absurd to suggest there wasn't at least some degree of astroturfing occurring on /b/ and /pol/ (aka /new/ depending on what time frame we're talking about) at a minimum.
It's important to remember that 4chan was a lot more influential in the past, and the anonymous nature of posting there would seem to me to make it an easy place for early astroturfing campaigns to manufacture their common ground.
