This mail list and its policies

I had no idea that my address was being broadcast to the world via
comp.databases.postgresql.general I have no problem with having messages sent
to the list go to the group. I do have a problem with my address out there in
the free and clear. Shouldn't the initial subscription notice let new sub-
scribers know that their address will be broadcast over the planet?

What's the logic and/or justification for doing this? I can handle the spam
using the delete key but I really don't like the additional burden that it
puts on my ISP. I would have posted via usenet had I known about this policy.
As a matter of fact that's what I intend to do from now on. Well this
address was good for some time and now it's tainted. The list owner
should send out as part of the pre-subscription message a warning that
the address they use will show up on usenet and the www.

Things that should be done as a responsible list:

1. warning in the pre-subscription notice about broadcasting the address

2. option to hide the sender, from addresses and any other address except
pgsql-general(at)postgresql(dot)org and any address that's in the body.

3. don't allow bcc to the list and don't forward messages to
info(at)postgresql(dot)org to the list.

I wonder how many subscribers to the list know that their address is
"out there" now? I suppose many have found out recently.
