The only thing I know that will get you banned is for using third party programs like a parser.
Lawl. In the 3.X 24 man stuff I've reported a few people who were controlling more than one character and admitted it (Admitting to logging onto friend's account/ect). Reported them mid instance, since they were causing issues in the raid rather than helping prevent them, and oh hey, they suddenly vanished.

You can only report it if they state it in chat in any shape or form, and only in the XIV game chat. Otherwise just kick said player and move on.
