I also agree that this is snooping. However, this is just a tool, and should be used responsibly. Abuse would make it reprehensible.
"how can you have a 'favorable reaction' to spam"
The intent is for people to lower their guard when they read email that's directly addressed to their name and seems to display knowledge of them.
"Abuse would make it reprehensible."
I think its abuse is being promoted, here. I mean, really, reread the blog post.
If you had to scrounge around to find my name and other details, or otherwise do something besides ask me, I'm not interested, just so you know.
If I ever get an email with my name from a company I've never given information to, I look to see any indication of how they got it - and then delete that email.
I'm sure the people whose eyes are lighting up at this idea don't care that some of their targets won't like this bit of cyber-stalking. I can only hope those who use it get more resistance out of it than responses.
