Resolved Question: I keep getting emails saying I have received my 1st to 21st positive message?

I keep getting these emails, they started out as ‘You have a positive message’ in the subject.
The email itself says wonderful! someone sent you a positive message!
Check out there photos and leave comments here (underlined)
and mousing over the hyperlink shows it is for www.optin.fanbox.com.
I have gotten those from ’1 message’ to ‘You now have a positive 21st message’.
I do not go to the website, and these messages go directly into my junk folder.
I have heard that the fanbox is a spam thing, and I have tried opting out to no avail. Do I just ignore them and let them go to my junk folder, to be eventually deleted? How can I make them stop?
