Seriously, if you never contact a contact, are they really a contact? But I'd agree with the others suggesting you accidentally selected it at some point. No biggie.

Could be for the purposes of being able to identify them if they do call/message/email you (even if you don't contact them yourself)? Maybe for the purposes of blocking them (in iOS 7)? Maybe just to keep the contact information for a "just in case" type of situation.
