Hi
As has been pointed out in the same thread if you can identify the people who are subscribed to the list indulging in such things feel free to notify the list admin and get the address removed. Unfortunately it seems that they are using aliases which makes it tricky if not impossible to identify the source. Hasnt this been discussed so many times already?list owner's commentary on subject... https://www.redhat.com/archives/fedora-list/2005-November/msg02632.html
