It is also usually applied to giveaways that are currently running (which the Joe Danger 2 Raptr Reward is not) and maybe for a little while after as the dust settles.
Using Raptr as an example, those Minecraft and Joe Danger 2 codes still required you to have an Xbox Live gamertag (and a valid Facebook account as some sort of verifier), plus experience in previous games on said gamertag.
You had to jump through a few hoops plus plenty of places that aren't Raptr threw out Minecraft codes like confetti. It seems the internet's handing out Joe Danger 2 like candy too.
Example: Since it launched I've had seven Minecraft codes cross hands, all from different sources. That one just kinda happened, funnily enough the one I redeemed was the Raptr one.
The Maw and R-Type giveaways required an Xbox Live Silver account. You can set one of those up in a few minutes. That counts as an exploit, hence why those codes were banned. Plus when that Raptr reward expired recently there were still over five thousaaand of those left!
tl;dr I'd wait until Shrike or Trakan or another mod makes a statement on the status of Joe Danger 2 codes. In the meantime expect to be lowballed like crazy. Supply and demand.
Oh and yes, you can put a "banned" item on your want list at your own risk. Sp00ge made that clear when he was a mod.
EDIT (I'm not making another post when this is one too many already)
By at your own risk I mean if you list a banned item them don't complain if a flood of users then offer you that item or you only get extortionate offers.
Oh well that's me told, thought you had to have a Gold sub. It still had prerequisites though, prerequisites it would have been difficult to meet a second time in the release window unless you have multiple gamertags you play the same games on like a silly person. Besides, I think no cost was required to obtain most of the things we have on our have lists.
