Phishing – How often do spammers, phishers, etc. change e-mail addresses?

Their only goal is to deliver the selected text block to the victim. Whether and how often they change a (fake) e-mail address is unclear, as individuals or marketing groups all work independently.

If an e-mail address is blacklisted, it is usually helpful to change an e-mail address, because in this case the message is not transmitted to the victim (spammers are stupid).
