It probably depends upon where you're looking. I never go to the front page, or even mildly popular subreddits for that matter. Ignoring the bot used for moderation, I would be surprised if 1% of the traffic on the subreddits I visit is generated by bots. It wouldn't surprise me if most of Reddit was like that, but you won't hear about them since they aren't the focus of everyone's attention.
