Of course most don't comment, but commenting is not required for a paper to be peer reviewed, only reviewing it is. If someone were to see the paper here, and review it, and find an error, presumably they would contact the author. 300k * 0.02 = 6000 people who may be qualified. How many people are typically asked to peer review a paper? A handful? The odds are still good.
