Has your blog content been investigated by some unknowns?

I was checking google analytics and I found that I had 1 particular visitor through google search for this search:

"wow….so arundhati roy candidly admits that her job is to only ask questions and criticize and not suggest possible answers"

That is from one of the recent posts on my blog. As you can see, it is too precisely worded to be a coincidence. And my website is the first link that comes up, the search being a 100% match.

I didn't do it, and niether did my co-author. So, SOMEONE checked up on us to see, presumably, if the content was original. Good for us that we write our own original content. But I was surprised that someone took the pain to do this. 

Has this even happened to you?
