According to Live Support Twitter, you can file a complaint against a user that has gotten a refund and still plays the game.
Heres my twitter convo with support:
@DrunkLastKnight: @XboxSupport Is it true that people that got a refund for Minecraft also got to keep the game? If so that doesnt sit well with me =/
@XboxSupport: @DrunkLastKnight We don't really have info on that one for sure. ^BB
@DrunkLastKnight: @XboxSupport Ive been hearing of people that have gotten refunds (some lying about it) and still play it essentially giving them a free game
@XboxSupport: @DrunkLastKnight Feel free to file a complaint against the user. ^PJ
In other words......get a life and worry about yourself and stop worrying about everyone else around you.
not really its no different than reporting players for hacking or anything else, its my right to report people if I feel they are breaking the rules, they wouldnt advise sending a complaint if it wasnt a valid one like marketplace theft.
