Because if it's not legitimate then it's worth knowing that? To me, this story seems far more suspicious than Fowler.
Does it even matter if it's faked if most of us could totally believe it's not?
Perhaps a variety of fake incidents have caused you to believe things that aren't true. Maybe the bigger problem being highlighted is also fake.
I recently had a conversation with someone telling me about a rape on a college campus. I told her I was skeptical. She said it was so common, why am I skeptical, and supported her case that it was common by citing Duke, Mattress Girl and UVA as examples. She was shocked when I suggested she google those incidents. Repeated fake incidents can cause people to change their priors.
So yes, the reason why "most of us could totally believe it's not" actually matters quite a lot.
