How to stop people who aren't your friends from tagging you on Facebook?

[Eden]

People can still tag me in their comments on Facebook--people who aren't even my friends on Facebook (seriously, we're not even FB friends).

I have my privacy settings enabled so I can review all posts I'm tagged in but when a non-friend tags me in a comment, it doesn't show up on my activity log and there's no option to remove it. I get a notification saying so-and-so mentioned you in a comment.

I know there's a way to prevent people from tagging you because I have certain friends and there are many pages that don't give me the option of tagging them in a comment with the "@" symbol. I just don't know how to get this for me.

I'd really like to know how to disable or stop people (especially non-friends) from tagging me on Facebook.
