Your talking about economics with an illegal or duped item. Theres no economics envolved with that. If you were a thief irl, and you stole something, you turn around and get rid of it as fast as you can, and turn any kind of profit that you can. Just like any duper with a brain would do. You don't hang onto illegal stuff, or make tons of it, thats how you get caught. Secondly if you dupe an item, then it's free to you, and anything you get from it is all profit.
Thats why when the dupes were going around prices on artis dropped super low, the dupers were trying to get rid of it as fast as they could and turn a profit. And the casual gamer only noticed one thing, and that was a bargain. Hence EA didn't feel the need to go after all the duped items, because the real victims were the uninformed gamers. And it wouldn't be fair to delete an item a player spent all their ingame gold on. So they turned their focus to the actual dupers.
Thats probably why none of the shrouds, vinecords, etc, will most likely never get deleted, unless your a moron with a chest full of them. Instead EA may one day step up to the plate and nerf it all by adding more items that are similar or better than the said items.
The whole point is, if there were thousands of these items going around, they'd be everywhere just like the changeling dupes were, or they'd be sitting in flames and rubble already.
