There are several other sites for earning online which have similar operations like answeree. I've worked a couple of them in the past and they turned out pretty alright.
Postloop is one of many such sites with user activities that revolves around posting questions, articles, replying and commenting, just like answeree. But there's quiet a major difference between both the sites. Postloop is like a medium, connecting users and forums to work together. And on postloop, points are calculated according to your rating's privilege, which is reviewed from time to time and awarded inline with individual performances. So the better content you post, the higher your rating, which also means you can subscribe to more sites and earn more points. 100 points on postloop equals $5, which is the minimum cash out. Asides that, it's basically a writing site just like answeree.
Another site worth mentioning is BMF. BMF stands for beer money forum. Just like other sites, this one too allows users to register and make post and comments while they earn. Their point system is quiet similar to answeree, every post gets a standard point.You need a minimum one thousand points to cash out. Another interesting part of BMF is their market place section. There you can find paid jobs or services with a predefined amount which will be paid if you choose to undergo the task. There are quiet a lot of task there and points can be easily piled up there.
I believe this are the two most reliable writing sites which I can personally recommend you try out.
