No wonder blueyonder have a problem when many of it's customers think bandwidth should be 100% unlimited no matter what. I always had a feeling that it's pledge to be the leechers best friend would end in tears.
I'm lucky that my blueyonder speeds are still quite good, but I'd happily accept a harsher fair usage policy or caps (especially if they allow a degree of flexibility and take into account off-peak usage), to ensure a decent level of service.
Blueyonder should stop pandering to the small minority of cry baby customers who kick up a fuss when they're asked to stop abusing their connection. When UKOnline first introduce their 8Mb ADSL for £30/month and the blueyonder newsgroups were full of zealots arguing that the blueyonder's 4Mb £50/month service was better because it didn't have the 500GB/month cap.
