> most of the content is just obviously bot generated

Either my BS detector is getting too old, or I've subscribed to (and unsubscribed from default) subreddits in such a way as to avoid this almost entirely. Maybe 1 out of 10,000 comments I see make me even wonder, and when I do wonder, another read or two pretty much confirms my suspicion.

Perhaps this is because you're researching products (where advertising in all its forms has and always will exist) and I'm mostly doing other things where such incentive to deploy bots just doesn't exist. Spam on classic forums tends to follow this same logic.
