No offence taken my man, I can see where it might be confusing to someone new. As it has already been stated, the items are purley collectible and cannot be obtained through farming.
now as for your "1."
The items/currency that is moving from the person Im trading to my items box are not being used as it anyway so it will not damage the economy, rather help it and this is why;
As of the moment all the currency that is being bid in my auction is unused currency. What I plan to do is move a few of my personal items in order to get all of the unused currency. Then through giveaways, in small bursts, inject that unused currency back into the community where it can be used, helping the community. ^_^
I hoped this helped you understand what my purpose is!
Questions and curiosities are never a bad thing, I'm glad you said something. I would much rather you ask "why" than to wonder "why". And who knows, this may have helped others too!
I only have this collection thanks to the amazing people I've met throughout this game, I'm just trying to give back to some of those people!
Your a good man deathdealer.
