I was responding to a claim that it was entirely spurious. It did show signs of being a copy of a portion of the image. It turned out that that portion was a copy of another image, which they (or their system) didn't realise. But none of this is (as the top post in this thread claims) just invented. Had 2600 copied that portion of that image, court action against them may well have succeeded.
All of this could easily have happened without an automated system involved.
