I think the phenomenon is explained by a little bit of A and a little bit of B.

The barrier to entry for internet communities has dropped like a rock over the last 10 years as smartphone usage has become ubiquitous. So you do have more average and below average intelligence (but still very real) people interacting online than ever before, by a wide margin from back in the mid 2000's.

I have seen the bot argument taken to the extreme by some when there was no indication it wasn't a person, so yeah it does get blown out of the water a lot of times just to try and shut down conversation. Even more so in political related discussions, people are so quick to call bot/shill on some topics, and I wonder how much of that has been influenced by the media narrative around the "Russian troll farms". One section of the population are entirely convinced that Hillary would have won if not for the bots/trolls, and use that to deflect from any other criticism of how she actually conducted herself / campaigned. Another section of the population looks at that argument as ridiculous, and dismiss bots/shill's as a delusion by the "other side" entirely.
