You want to sell me a list?

Over the years, some of my clients have found it expedient to give me email addresses at their domains. These addresses forward mail addressed to laura@clientsite to my own mailbox. Generally these are so I can be added to internal mailing lists and have access to their internal tools.
It’s often amusing to see the spam that comes through to those addresses. Over the last few weeks I’ve received multiple spams advertising an email appending service.
Let the irony sink in. An email appending service is sending me an email at a client company offering the client company the opportunity to append email addresses. “See how accurate our appending is!”
How accurate can a service be if they can’t even target their own spam correctly?
In addition to the appalling targeting they’re also violating CAN SPAM (no physical postal address), their website is a collection of broken links and they don’t provide any company name or information in the email or on the website.
To top it all off, the mail says, “if you’re not the right person to act on this mail, please forward this to the right person.” Followed by a standard legal disclaimer that says, “The information contained in this e-mail message and any attachments is confidential information intended only for the use of individuals or entities named above. If the reader of this message is not the intended recipient you are hereby notified that any dissemination, distribution or copying of this communication is strictly prohibited. If you have received this communication in error, please notify us immediately by e-mail at the originating address.”
I wonder if blogging about the utter email incompetence about mail from David Williams, Business Development (phone number: 800-961-5127) violates the confidentiality clause?
