To the best of my knowledge, Google NEVER releases what you might consider to be "helpful information." There's a simple reason for that--if it's helpful to you, it's also helpful to someone who is trying to figure out how to generate invalid clicks and get away with it.
What about if there are NO ads on your domain. You had taken the ads off for reasons best known to yourself and G sends you an invalid clicks e-mail. Then won't tell you what url is providing those clicks (clearly it isn't your own so it must be someone elses domain that they are being shown on). Far fetched -I'll show you the e-mails!
