Using the link-level address to distinguish between good and bad email content was always daunting at best. Thanks for pointing out that this flawed behaviour must cease.
I don't know anyone who does that. But I know a lot of people who use both IPv4 and IPv6 addresses to distinguish among "has sent legit mail", "is a spambot", and "no history". Those are handy when mixed into the usual multi-factor spam filtering. Outright blocking on conservative lists of spambots like the CBL (now XBL) works well, too. R's, John
