Oh wow, I have a special hatred for them. I bought one thing from them and then spent years trying to get off their email lists. It took me something like 12 separate email requests (plus who knows how many times clicking on unsubscribe links). As a company they are dead to me.

I was just in this dilemma to begin to eliminate accounts and random stuff I signed up for in periods of my life that are long gone. Many of them still have my email for some registration I made but have since eliminated all the emails and only get these annual privacy notice updates that seem mandated somehow. Even those I don't welcome because it's just another distraction to have to bother with.

At some point I wonder if these organizations realize that if they continue to dishonor unsubscribe attempts that they simply get marked at spam. In the context of gmail I always thought too many organizations that get marked as spam just hurts them beyond the user they did not honor. Does anyone know if this is so?

Yes, I read the book and it is quite good. That is not the merit of the publisher, but the merit of the author. You can buy the book (more or less) directly from the author on https://leanpub.com/get-your-hands-dirty-on-clean-architectu... , so PacktPub seems only to be the printing partner.
