I fully understand how you feel and appreciate the outrage. I too have been plagiarised, a lot. I tried to track down the perpetrators on some of the free blog sites, to no avail. When my book was plagiarised by a very well-known person, I went to my publisher and they decided not to pursue it. What’s a writer to do? The only concession I can give is that true writers, authors, journalists would NEVER do such a thing as we respect the art and craft of writing as professionals. At least I’d like to think so.
