I don't think they promised those in FOM would earn 4X more, but that our reads count/pay 4X more, unless I am mistaken. I can't attest to this though, it seems pretty hit or miss. I think some find being a FOM attracts more reads likely in hopes of return reads, I honestly haven't seen a difference. I joined with the sale price and pay monthly so I am seeing how it goes. There really isn't much in it that I can see other than hopefully some are benefitting from it.
