IPhone 5s :: Can One Prevent Changes To Their Contact Book

My brother is 22 was gifted an iPhone 5S. It has greatly aided in communication skills and growth with family members and close family friends. Due to this, he has gotten ahold of our large family phonebook and added every number, home/work/school email/physical address, birthday, etc. to his Contact Book on his iPhone. However, some of the contact information we have isn't valid anymore and yet, he still contacts these numbers via text, phone call, or email.

After logging onto his iCloud account and deleting these outdated contacts, he cleverly re-added these numbers in. We want to give my brother his privacy to communicate with family/friendss, but we do not like that he keeps trying contact these outdated contacts.Â

Is there a way to prevent the addition or edit of contacts in his contact book? I understand that there are parental controls that allow one to prevent the addition, edit, or deleting of mail, contact, or calendar accounts, however, it doesn't seem to disable the addition/edit/deleting of actual contacts. Ideally, we'd like to be able to delete numbers and addresses that aren't valid, and then "freeze" the addition of more numbers from him...Â
