Persian Facebook applications

I have done few experimental applications 3 years ago on Facebook on a trial web host, when the trial was over the applications died, although they had thousands of users. Last month I'd get time to try the old experience again and bring those apps back to life. After a month one of them has more than a thousand users So it seems like a good market but I can't make any money out of it. :(!!! And this is another one which I've got hopes for it to be popular.
