This has been obsolete advice for over a decade.  It's now folklore,
not sound operational practice.  You should assume that spammers already
have any/all email addresses and plan defenses accordingly -- because
even if they don't, they will soon.  Please read, in full, these messages
where I explain this in considerable depth:

As an addendum, let me point out that since I wrote those messages, we
have seen one massive email provider compromise after another -- most
recently, 500M+ accounts at Yahoo.  Of course all the former owners of
those accounts are the "Fred" I discuss in the second message above,
and they join all the other Freds from all the other mass email provider
account compromises we've seen in the past few years.
