Interesting: that reinforces LOTR's mention of bogus Ultrapeers.

Every time you connect (or leave LW running for long periods of time, you likely connect to different Ultapeers, so maybe yo are now connected free of the blockers. Still, I'm doubtful there are UP's that can channel AND restrict downloads from sources like magnetmix.

With a dynamic distributed network like gnutella that has no central controlling servers, it's very difficult to say.

Maybe your discussions with your ISP finally trickled through to the right person

Anyways--cheers.
