This sounds like really bad advice to me. If one were going to set up a spam/phishing operation then the first thing would be to choose a domain like xyzcorp-messages.com. I'm sure that the blacklists look at domain age and prior performance too. Anything marked spam from a brand new domain, which appears to be a phishing domain, that has no history of not spamming associated with its ownership is surely going to pop into a blacklist faster.

You have some evidence experience to back up your suggestion?
