Do you report people in-game because you're offended or to get them banned? Both?

Something interesting I've been thinking about. I disagree with some of Riot's rules so naturally I shouldn't report people, but a part of me takes joy in getting peoples' accounts banned. Is this a functional system where I report people to get them banned instead of reporting them for being offended? Is it morally justified to report someone for rules you, at heart, disagree with?

We're testing a new feature that gives the option to view discussion comments in chronological order. Some testers have pointed out situations in which they feel a linear view could be helpful, so we'd like see how you guys make use of it.
