Anyone attempt using these? Anyone crazy enough to try them out? If anyone doesn't know what I'm talking about then check this out They just seem really fishy Some of them ask for your Gamertag, password, and associated email... big no no. Really though I'm kind of curious if some of them work. EDIT: just got to thinkin, hope this type of post isn't against any of the forum rules, if someone believes it so, give me a heads up and I'll remove it.
