To be clear, that is exactly how professional propaganda operates. Their goal is to deceive people; blatant lies obviously won't accomplish that, just like blatant phishing attacks will fail. If you can tell it's propaganda (without knowing otherwise about the source), it's not very well done.
AFAICT, humans greatly overestimate their ability to know propaganda when they see it. We all think that we can't be fooled so easily, and that's exactly what makes us vulnerable. We're naturally persuaded by things that don't correlate with truth - you can see that in the accomplishments of endless false political leaders, and their propagandists, throughout history.
However, I also googled "steubenville hacker"[2] and found a number of other articles confirmed this story. Most were published in the last 10 hours so I'm confident that major publications aren't avoiding this story because it's false, but rather, they haven't picked it up yet.
