Isn't doing something that is legal but goes against the spirit of the law by definition exploiting a loophole? Edit: now that I think about it, there is room for a distinction between areas where case law hasn't ventured and exploitable holes in areas that case law has explored. But I'm interested in hearing if there's a more formal definition.
