Bloglines zombie

Now that I have left Bloglines and use RSS Bandit, it came to me that Bloglines is still fetching all those feeds in my name. So if Feedburner reports 9 Bloglines readers, I really should subtract one of them, since I am not using Bloglines anymore. Of course I could go back in and delete all my subscriptions, but nobody ever does that, do you? I wonder how many of Bloglines’ reported tens of thousands of people are zombies like me, still subscribed to feeds but not actually using Bloglines anymore to read them. And does Bloglines disable accounts after a certain period?
Of course the same goes also for other web-based feed aggregators.
