Hi thewildblue and all,
I am sorry to hear about your ISP - it is very unfortunate that some ISPs, especially in the UK, claim to offer unlimited broadband but in reality they cap it at some ridiculous figure - reporting them to ASA is a good move, they should not be able to get away with such misleading advertising that gives them unfair competitive advantage!
Good unlimited ISPs in the UK are Telewest (cable), BeThere.co.uk (ADSL 2+) and (yeah I know it sounds aweful) AOL... there ought to be some more.
However the main point is that while running MJ12node is perfectly legitimate, it is best to keep under the radar - we have a lot of people crawling, and while I appreciate the desire to crawl as much as possible and max out things, it might be better to crawl less just to be sure: better crawl at 1 Mbits whole year, than crawl at 5 Mbits for a month: as we get more poeple joining it will allow individuals to crawl less URLs thus being under the radar of some of those ISPs that are not particularly honest about what they sell.
Traffic counter shown in node should be reasonably accurate, so don't push it hard - unless you are sure you are on Unlimited ISP of course.
Sadly there is no way around making MJ12node use less bandwidth - we can't crawl page without having it transferred and sadly vast majority of servers do not even support gzipping content
