I don't know if anyone noticed a large ad on VIN, but just in case you didn't, there is a large ad on VIN advertising that they will give you $1600 for opening an Amex card.
Presumably, this guy tells you to open the Gold Biz card or the Plat card, spend money on it (though I don't know how) and then to call and match it to 100k MR, which he then buys off of you for 1.6c per point.
I don't know if this guy is part of the Dans Deals forums or not, but all I can say is that this is extremely idiotic and very pathetic. This is complete exploitation of the MR program, and may cause Amex to stop matching the MR points.
It is one thing to "share this deal with your friends", it is another to make a business out of this.
There are thousands of readers daily on VIN.
Just sharing my thoughts...
