There are several differences between mail addressed to an individual
and mail addressed to an open mailing list:
* Users know whether or not their messages reach the list. If there is
"spamicity" in a legitimate email, users may remove the spamicity and
resubmit again.
* Every spam addressed to a mailing list which is not caught by mail
filters in the list servers is multiplied by several thousands when
delivered to subscribers. This is a very high price to pay and it's not
comparable to the price if the address were an individual address.
It's very easy to say "lists should remain fully open for all posts
below 5.0" when you have a fast net connection not everybody has.
