Possible market board exploit

[KageTokage]

You can simply make use of a mannequin and sell your alt a piece of armor you crafted for 1g and sell it in the alts world if you have a single account. Anything else is going to require a second account, a friend to pass the crafted items and mats to another world with an alt.

I've seen even consumables bearing the name of a player who can't craft, so I'm not sure what the deal is with that.
