Hi.
Just hacked this out myself last night.
First, you need to see if your ISP has an uncensored news server (my old ISP used to filter all alt. groups, my new one has everything). If so, good.
Then you need a news browser, and in this case one that can decode yEnc. (I was using Free Agent, but no yEnc support. I tried using a standalone decoder like yDec, but Free Agent was corrupting a straight save of the encoded text. ) The person who posted the material was using yEnc, a new relatively high performance compression algorithm.
I just got good results with Super Gravity, Google it, it works and it's free.

Configure for your news server address, and aim the browser at alt.binaries.nospam.breasts.natural
and try to look at 12/5 at about 1:30PM. You will likely need to sample more than the default limit(2000) - I had to boost to about 6000 last night to go back far enough to see the right messages.
Read the docs, download, decode and view. Good luck.
