Sure, but most spam will go the other way. When you're in a forum and you express an opinion that doesn't fit what the bot swarm is designed to police, they will gang up on you and argue against you from various angles, and you'll think your opinion is just super unpopular. If you are a famous person they'll do reputational attacks, after amassing karma points and followers across the swarm. Then they'll move on to combating the remaining human-powered outlets like nytimes.com, becoming the next Vox or Vice, but totally AI-powered. Their bots will spread their articles over the other ones. And finally, having driven humans underground in the dark forest of social media, they'll basically dominate the Internet.

The real sea change will come, though, when bot swarms control capital. For example, amassed for doing spam tasks. That capital can be deployed in a variety of ways, but the point is that corporations and networks will prefer bots because they generate more social capital, in coordinated ways, and also amass more financial capital than humans.

If you think this is far fetched, IT ALREADY HAPPENED on wall street and hedge funds. Bots have replaced people in trading and control the capital. Humans who trade among the bots get fleeced and don't even know it.
