Should academic CVs include reviewing, non-academic service, hobbies and languages?

Do you suggest adding these to an academic CV?

• Review journals/conferences. Can adding such information creates negative issues or it would only have positive impression?


• Non-academic service: example, Unesco volunteer


• Hobbies. Many sites suggest to remove them http://ift.tt/1q97PU4 , but isn't it important to show that the applicant is not a robot? Some suggest to include them wisely http://ift.tt/1yX0xDB


• Languages. Can knowing a certain language be used as a discriminate against an applicant?!
