I've shared over 5000 files before .. I don't anymore because OSX's Java can't handle it. And I've seen others share up to 15+ k files or something.

I agree that the lady definitely has room to appeal against such a fine. It's an exagerated fine. They do this for propoganda reasons to show to the media to try to scare people. But they won't report court appeals that knock the fines back to a small $ % of the original fine.
