Mail Chimp

My OS is win 7 prof 64 bit and I am on a web site's email List which is run by Mail Chimp.  My email is msn the free version, and I use the web to read my emails.  
My question is, is it possible for any one to receive my email and unsubscribe me to the site's mail list.  Or is it , the only way is for the moderator of the site to do it.
this is because I received a message from the site to say that I had unsubscribed, and whether I really meant to do this.  So i had to go back to the site and re enter my name and email again.  
thank u for your response.

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

If an admin/mod removed your subscription you would not receive an email telling you that you unsubscribed.

Probably someone used the Unsubscribe link in one of the emails. It's of the form

Anyone can unsubscribe you is he/she has that link. Maybe you forwarded one newsletter to someone?
