These two sites are free to register, but they waste your precious time by directing you to post their sites ads in different places. The home page of the site was very attractive and it said we can earn monthly huge dollars, without any investment. So I registered there, but once I signed in I came to know that it's also a kind of scam. The contents of the members area page was not relevant to what had been written in home page. It just told members to place their site referral to many classifieds and blogs. There was no actually data entry work.
