I stayed at the Westin last Saturday night.  When I made the reservation, they asked for my email address so they could send me a confirmation.  I asked at the time if they would use my email address for anything else and they assured me that they wouldn't. 

This morning I got an email encouraging me to come back and visit the Westin again.  I guess I expected as much -- no big deal, I can just unsubscribe, I thought. I'm usually easygoing about such things. When I clicked the unsubscribe link though, it took me to a page where I needed to create an account for myself before I could log in and unsubscribe.  Now that is a crock.
