Applying patches from gmane can be dangerous.

[Junio C Hamano <gitster@pobox.com>]

I picked up the qsort patch from Brian while reading the list
via gmane's newsfeed and applied it without realizing that it
was one of the articles whose addresses on all the address
header fields _and_ all strings that look like e-mail addresses
have been mangled by gmane.  Sign-offs by Dscho and Steffen
Prohaska have also been munged (even though that are not part of
headers).

It already is part of 'next', and we have the policy of not
rewinding 'next', so the record of this mistake will
unfortunately be with us forever.  Sorry, Brian, Dscho and
Steffen.

For the curious, the message was:

    http://article.gmane.org/gmane.comp.version-control.git/72699/raw

I've added the following in my .git/hooks/applypatch-msg and
made it executable, so hopefully it won't happen again.

    #!/bin/sh
    case "$GIT_AUTHOR_EMAIL" in
    *@public.gmane.org)
            echo >&2 "Gmane munged the author's email address, aborting."
            echo >&2 "Pick up the original message from your mbox!"
            exit 1
            ;;
    esac

This is really sad.  gmane gives us a clean threaded interface
(both in web and newsreader), and it never forgets. Whenever I
need to refer somebody to an old discussion, I can give an URL
to it and allmost all the discussion messages are there with a
single paste and clicking around.  It has been an indispensable
service to me ever since I started reading the git list with it.
It is really a shame that I have to prevent picking up patch
messages from it with the above hook.

I am wondering if other development communities had a similar
issue already, and if so how they are dealing with it.
