This reminds me of "Why is there tele-marketing when everyone hates telemarketers and getting calls at 7pm when you are sitting down to dinner?" Because it worked! It was profitable. Now, interestingly we then hit a tipping point where there was enough outrage (US) that a "Donotcall" list was created - very effectively. How long till there is a "Donotemail" equivalent? The industry is arguably not policing itself well enough. I'm really glad the CEO showed up her to defend his/her company but "Hey guy didn't pay enough attention so what are ya going to do?" is too cavalier. Imagine if social services had to check all email addresses given out like this against a central list to see if they were on the "no social offers no matter what"
