I think it would. Most spams have forged headers, and rather than being
complete faked addresses, they're addresses belonging to someone else.
It's an old trick to spam someone so that rejects become spam to yet
It'd be different if you could reject during the SMTP stage, and a
poster's attempt would fail during the attempt, not after. But very
very few people make a direct connection to the end SMTP server, so that
doesn't work any more. They send to their ISP, it accepts, and forwards
on. SMTP rejection is too late, by then.
The list becomes a potentially *large* source of spam, when rejecting
mail to a third party.

Don't send private replies to my address, the mailbox is ignored. I
read messages from the public lists.
