@XanderHenderson @quid @DanielFischer: Please note the behaviour of this moderator in not locking the question despite being made aware of the cheating attempt.
Underwood Dudley published a book called mathematical cranks that talks about faux proofs throughout history. While it seems to be mostly for entertainment than anything else, I feel it has become more relevant in modern mathematics. Especially with the advent of arXiv, you can obtain research pa...

@amWhy Well at least this one isn't a crank. But it's kind of annoying that there are so many people that think they know everything when they can't understand even basic logic.
@quid To go back to my default state, I don't really care to adjudicate whether or not someone is cheating---it doesn't matter to me. The issue is that the question is part of an ongoing competition, and should therefore be locked and invisibilized until such time as the competition is over.
