Oh wow, that's terrible. I had stopped using MFF a while ago. I had spoken with the owner a few times (through the forums and support tickets) and she seemed like a really nice person.
MFF used to be the easiest way to get points, back when it first started. All you had to do was enter your email or zip code, and you would get $1 each time. I made a couple hundred dollars in a couple weeks, haha; it was great. Then they changed it though... and made it more difficult.
Right now Prize Rebel is all I use at the moment, so it's all I can really recommend. Referrals are the easiest way to earn stuff for free, if you can get them, that is (Lately I haven't gotten any). I've noticed a general trend though: in most cases, the newer the site is, the easier it is to make money/get credit for your offers. You just have to be willing to trust it. I joined PR and MFF within a few months of their launch, and was definitely earning the most points then.
