So we all no that the "get your ex back" niche is a pretty profitable one, simply because of the emotions that it plays off.
What I don't get is all the copies and variations of the content online. To my knowledge, this sort of Intellectual Property can only be protected by copyright. It can't be protected with patents or anything else stronger than that.
Even so, why do people still go about blatantly plagiarizing content and where do you draw the line?
