Wow. I have never gotten a notice myself and I download torrents constantly, often 24/7 (slow upload speed). I wonder who your ISP is? To get around notices most torrentfreaks use VPNs', I just use Peerblock myself (blocking 1 billion IPs and counting!). If usenet works for you then by all means use it. though you could have all 4 seasons downloaded in a 13 GB torrent in a pretty reasonable time in very nice quality......I don't know if you can get that on usenet or not, never used it myself.
Happy Pirating! (I actually prefer the term "filesharing" though. I have never considered what I do as stealing. Someone paid for it, ripped it, and shared it for free and I watch it and delete it. What the fuck am I stealing? If you steal something, something goes missing. The thieves are the ones who overcharge for it so I can't afford to see it otherwise.)
