It seems to me that komponisto's The Amanda Knox Test similarly made a case for "not guilty" without reference to the all of the arguments for "guilty", and had other substantial flaws. But it's at 29, compared to Rolf's -10.

That is not similar to stepping into a giant past discussion without referring to it. Kompo started a giant discussion. He would have been downvoted mercilessly had there been a preexisting bloated corpse of a thread on the topic.
