Consider a bot that posts around 300 comments a day. It probably makes 20-30 GET requests to Reddit per minute. Let's say on average it gets every 25 seconds - that's roughly 3,456 GET requests every day. So this bot hits servers 10 times more often than it posts comments, so you can see how its visible behavior is dwarfed by its background behavior, which is actually a bigger technical concern for Reddit.
