Banning users from a Fan Page

I wonder, is it possible to ban a user from a Facebook fan page if they have not commented on, or liked any posts.

I ask because I have been receiving unwanted messages form a user, but I seem to be unable to ban them because they have not "liked" or commented on any posts, so I can't click on a cross next to their name anywhere.

I have searched BHW but this doesn't seem to have been mentioned anywhere else.
Many thanks in advance

Yea you can ban him where he made a comment,post on yur page there is a cross mark you can click it and bann him from page
and if you want to bann someone from page that don't comment or post but message you there is a tutorial here take a look at it for banning any member from your page

The art of working all these social network sites is capturing all the negative and positive visitors and comments and using them to benefit you... the answer is not to ban them or get them deleted...

Rupert Murdoch built one of the biggest companies in the world using all the negatives and positives making them a plus for his companies, he does not even give a sh1t when caught phone tapping on a massive scale...

Folks learn a lot from major players who game the establishment...

Of course you can ban them. Just visit the post and under his/her comment, there is a option to report/ban user.

I Have banned 100 user from my fan page by doing this. Just do which Sir Roshaen say.

I agree that negative and positive comments are beneficial and necessary for improvement but if it can disgust you, then ban the users.
