text: you can't "ban" anyone from myspace; that's the site administration's job. but, you can prevent the person from sending you messages (by going to his page and clicking "block") and/or prevent him from viewing your page (by going to "account setting">privacy setting>change setting>who can view my full profile>my friends only. when you do this, you will also prevent people who are not on your friends list from seeing your profile as well. so, in short, you can't just ban one person from seeing your page).
