4chan flocks to doom and gloom predictions, because that's the most "fun." When they always predict a global disaster, we shouldn't be surprised when they predicted something that actually was a global disaster. Broken clocks are right twice a day.
More like, '4chan predicted 10 of the last 1 disasters'. Still worth checking in, just in case this is the one that pans out. Definitely better than ridiculing all 10.
