Whether this is a fake or not will be found out soon, since if this is true they will start to pop like popcorn in different MS sites.
Regardless, using the REDcard recklessly is stupid (sorry for being blunt). This is a very generous MS vehicle, with just one Redbird you can make $100/month by simply loading and doing billpay for the 2% cards like Citi doublecash, not do mention the 5% venues, scarce as they are. Be content with that and don't suck it dry on an ATM, don't deposit the bulk of it into your checking acct etc.
Basically, use common sense and have at least minimal impulse control. This is for YOUR OWN good, not mine/ours/others.
