The reason why you saw that was because it was a scammer. It's a common scam that has been used for a while. The person with the rares askes for a fairly uncommon item that most wouldn't have. Then their spare or a friend comes over with the exact item on their trade. But they say that they don't want the black longs, maybe they want a red long instead (wich obvously would be a scam since black longs are worth WAY more than a red long). And you happen to have a red long, so you think "Oh wow, i can get this item for my red long and then trade it to this other person for 3 black longs!" Then you do the trade and get the demon mask, and the person with the black longs, and their spare, leave. And you are left with a worthless demon mask, and the scammer just gained a red long.
