Cross posting etiquette

Hey,

I am getting very annoying with all the cross posted anouncements
being made to (I assume, though I can't be sure because they are all
BCCd) this list.

I have two major problems with this:

  1. I have a set of local mail filters which process mail according
     to the TO/CC headers and BCCing in who knows how many mailing
     lists totally breaks this, and could be considered very rude.

  2. I don't actually care about the last call for papers for some
     conference and feel this might be better placed on a specific
     announcement list. These announcments never seem to generate
     discussion so I feel that thier place on a discussion list (I
     assume that purpose, I may be wrong) is out of place.

Perhaps there could be some form of W3C lists etiquette drafted or
even some technical measure to rejct mails that don't explicitly list
the mailing list in the TO/CC headers.

I'm fairly new to the list, so sorry if I am covering old ground.

Thanks,
