I found this page, the author has some tips on how to be removed from most major ISPs blacklists ... obviously they won't approve heavy spam complaints but this does show you where to go if you think you have a chance of getting removed. http://www.rackaid.com/resources/spam-blacklist-removal/
Some good info on there man, nice share! actually saved me some google time, I was actually doing some reading on this earlier today!
i have got feedbackloop removal with interspire so it removes fbl automatically. Anyways thanks for this
