Besides my subscription to CR4's Daily Digest I also subscribed to some of CR4-GlobalSpec's product alerts. Sometimes I click the "read more" buttons in these brief headers to check if the product is indeed of interest to me.
Lately I have received several unasked-for emails ~usually referred to as 'spam' or 'junkmail'~ from companies mentioned in these alerts, even without actually having visited their website. The only explanation I can think of is that somehow CR4-GlobalSpec enables these advertisers to know my email address when I click the "read more" button. I would consider that an unacceptable privacy violation. But really, I can hardly imagine CR4 to be promoting this kind of obtrusive spamming.
Can somebody please explain?
