I will give you a

you are still on the top of my list!
Still I think that by releasing some of the more rare things or by taking them from the scammers and "Yard Sale" ing them it would put more into circulation and by no means am I talking making items worthless.
I think that say timed sales for rare items would be awesome...it would be just pure luck as to when these items pop up and who is in the game to get them.
Here is what I would love to see:
Rare Item, lets just say green flips, for sale at 12 noon on Saturday for 30minutes for 2000 credits limit 1 per player.
even 15 minutes would increase circulation most would buy for their main and then bring in their other characters but with only 15 minutes to be able to buy and only 1 per player that would increase circulation and deflate the resell price not totally devalue the item.
They could reintroduce the same item all month like this having it just pop up at various times and for extremely short sale times.
What do you think about that A? would that be a feasible alternative?
I am trying to figure out a way so not to devalue rare so much that big traders will lose interest and drive in trading but make items more obtainable for others, thus decreasing the scammers scams.
I know it will never do away with them completely but it would take a bite out of their crime.
