Basically a player created a Reddit post about a get quick rich scheme about creating a cheap Legendary, bought up all the mats he claimed he used at a low price and sold them for high before the Reddit users caught on to the scam. I thought it was pretty damn funny that people can get sucked in like that.
Here's the Reddit post about it. The post does have interesting things to say about how the market can be easily manipulated if you don't do proper research.
