I just followed a link in a Target email to unsubscribe from the Target.com mailing list.
To my knowledge, I have not received any spam from this site.
This was the link I was led to when I unsubscribed to Target notices.
This is easily unsubscribed from. Target is a reputable company, and I have been doing business through their site for years with no problems.
This is the Target weekly ad redirector, it redirects to a well known company, Target.
I have been surfing the Target site about once a week for a while without any problems
