I say we turn the tables. Let's stop using words like "paranoid" to describe people who want random strangers to leave them alone. Instead, let's choose a word that's the inverse of "paranoid" to describe the asshats who intrude into the lives of others and then claim that data as their own to use as they please. I tentatively suggest "Orwellian" but am open to suggestion. Maybe Panopticonians would work, except that fewer than six syllables would be a plus.
How about "data nympho(maniac)s" or "data sluts". They have the abnormal drive to give their personal data to everyone. "nymphomaniac" is also a good counterpart to "paranoid" because it's derogatory and (at least used to be) a medical term.
