No, it isn't. It's a nice excuse for taking someone else's work, but speaking for myself, it's no compliment.
Bob and I put in a lot of time and effort. Someone coming along with a copy+paste? Nope. Not a compliment.
Want to compliment something a writer does? Leave a damn review. Recommend the work. Drop a private message. Don't steal it.
Oh...and hi everyone!
