1. This would be really really hard for us to police. At what point does it become a monopoly? What do we do in that case, close their shop? Distribute their items somehow? I don't really know what we'd do.
2. We try not to control the market too much, except to do things like take sP out of the market (which, by the way, users have spent 1,587,600,000sP on the Zapper experiment only zap :thumbs_up:)

Basically this is a game. The people who buy up all of those items are playing the game how they want to play it.

ALSO if we see this happening we typically tweak those kinds of items to try and get more of them out ;)
