AT&T has banned a friend permanently so I would be careful about over-broad generalizations. Folks in my my household were torrenting and we got our service cut with the second offense until we went through some rigmarole promising we'd never do it again at which point they stopped. The cost to an ISP's lawyers to field these things isn't free and at least some really do respond with action.
