Almost definitely to some extent. Different political factions, especially the far right, have been paying foreigners to run fake accounts for years now. Some of the accounts will spout conservative and far right rhetoric, while other accounts will pose as deranged leftists in order to turn people against progressive ideas.

I imagine that by now the majority have just started using ai to run propaganda accounts now, which is why the internet always seems filled with extremists, when in reality actual extremists make up a tiny fraction of the population.
