This already exists. It's not just for verified Twitter users either. You have used this "database" yourself. You and your family are already in it.

When the outrage reaches it's peak, the name of the "database" will be revealed:
It's called Google+Facebook+Twitter+LinkedIn+Reddit+Yahoo+Amazon+Apple+Youtube+Pinterest+Instagram
