Online plagiarism

There is so much plagiarism online. I came across some text and was reading thinking wow, this guy really did some research, and then I started to realize it was written by me, just no reference that it was written by me. I think referencing is relatively a new thing anyway. What they did back in the day was include the name of the text and the author in the book itself. And poets would somehow work their name into the ending of the Poem. So as weird as it may sound, this is what I am doing from now on.
