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.
