Plagiarism is nothing new to me, sadly. My work has been plagiarized several times. Never my fiction, always my nonfiction.
The first time was a few years ago. I’d given a presentation to a Sisters in Crime chapter. Twenty-four hours later the handout I’ve given out during the presentation came back to me as part of an email chain but with my name had removed from the piece. That was more of a piracy than plagiarism but it made me aware of the situation. After that I set up a number of Google alerts to alert me when key phrases of mine are used.
Doing this has proved useful. Over the years, I’ve discovered a number of people who’ve repurposed my work. In some cases, it’s just ignorance. “What do you mean I can’t copy and paste your work into my blog and not give credit?”
One of the more egregious examples came in the guise of a “writing teacher” who essentially copy and pasted articles from Writer’s Digest’s archives onto her blog under her name. Someone who recognized the piece called her out and a dollop of public shaming ensued. The woman apologized to her followers but doubled down on her error and showed her ignorance of plagiarism and intellectual property by then paraphrasing my work and calling it her own. Sadly, despite all this and a public apology (not to me or Writer’s Digest), her followers still congratulated her on “her” insightful writing. I think that irritated me more than anything.
My normal response to plagiarism is to check whether the plagiarizer is making any money off my work or not. If they’re not, I usually just let it ride because I’ve trying to explain the error these people have made has proved more difficult that I would have thought. It’s surprising how many people think they’re not doing anything wrong.

This has been a harsh lesson that I have to learn from with future incidents. I hate being a dick but I don’t think I have a choice. So no more Mister Nice Guy. You’ve been warned evildoers.
