Correct me if I'm wrong.
With the Corrupt Mind skill, Trade is a Basic Action, yes? So what's to stop the Darkness player from simply selling all their victim's equipment?
Two major things actually. ^^;
1) Players DON'T have access to enemy player character sheets, so they don't know what they would be 'selling' to begin with, even if they saw part of their deck in the previous battle; they can't physically change that character sheet either, so it won't work.
2) They'd have to be near a city to do this. (Lesser reason)
Personally, the real damage you can do with a controlled player are:
-Using the person to attack members of their own faction
-Using the person to protect you from oncoming attackers
-Using the player to SEIGE THEIR OWN TOWN (

)
-Moving them into random territory and neutralizing hexes to other enemy elements
You can't sell off their entire army obviously, but forcing them to damage their own settlements or ruin their reputation with their own faction is quite fun in my opinion. ^_^
