CrowdGen aka Appen

I have been looking over some of the older "Who paid you" threads and noticed that I am not seeing any mention of Appen not called CrowdGen. Why is this? Is the site not that good for work? I have recently started looking at it again and have taken several tests and passed them but I am not seeing any work from them yet.

Is CrowdGen a viable site to make money from? In my opinion so far it is not fairing that well but then I have not put much time into it yet.
