That was my first thought too but I looked at the list of claims. They're all very US centric and I hadn't heard of any of them, but none obviously jumped out as true but rated false. There was one about a fabricated quote assigned to a US politician, and I couldn't find any original source for it (and it was suspiciously extreme anyway).

At the very least if one was incorrectly classified you'd need to do some legwork to demonstrate that.
