Blackballing, in Victorian English society, strictly meant to vote against a proposed member joining a club (above the working classes club memberships carried great weight wrt social standing).

It was also synonymous with ostracism, to be excluded from society, to have little to no chance of regular financing or loans, to have debts called, to be fired and have little hope of being employed.

It was socially networked suppression, operating at the speed of club dinners and afternoon teas.

Such things go back in time in many societies, wherever there was a hierarchy, whispers, and others to advance or to tread down.

If we are looking for synonyms with related effects we should include banished, excommunicated, shunned and interdicted.

They have all slightly different meaning, used in slightly different contexts, with a slight different effect on the individual and community. They can't be used interchangeable without loosing that distinction and creating slight misunderstandings (as well as originating from different cultures and religions). We might say that someone should be banished from polite society, but we can't say they should be interdicted from polite society.
