[Icecast] Help with list maintance

[David M. Zendzian]

Hello,
Since the list was upgraded I have noticed i am getting 2 copies of each message.  I only today had a chance to look into this and wonder if someone can help me figure out what's happening & clean up my list subscription.
For every post I am seeing identical posts from 2 different hosts:
1) westfish.xiph.org
2) master.debian.org
I am guessing that there is a listserv running on both, but don't know how/when/why debian started mirroring the icecast list.  Any thoughts/comments?

Thanks!
David
