I found some of my stuff pirated once. Very, very frustrating. I understand your feelings. What I consoled myself with was the idea that, in the modern internet universe of things, getting content out there often has roundabout benefits, drawing more eyes to your work and delivering peripheral advantages.

This is by no means an effort to say "dont' worry about it," because believe me it still pisses me off, but I figure we always have to look for the positives in everything, and even if what this woman did was unethical (and I fully agree it was unethical), perhaps the audience she reached might have somehow ended up benefiting you.

anyway, those are just the thoughts I had to ease my anger.
