App is Not that good. Review on Mouthshut

I am using mouthshut app from 10 to 15 days. The app is providing a platform where u can share your experience of using any product, website, app, etc. And they are giving you money in the form of points for your each review. An app provides the user to review the product before purchasing it with the help of real user experiences. I have written 6 to 7 reviews until now . They have approved my 3 reviews and paid me 120 point. But now they are taking too long to approve my reviews and this is quite disapponting. I have convinced to two of my friends to join mouth shut and they have referred my link but after 6 to 7 days I didnt get any point for an invitation. One of my friends has gotten above 500 points and he tried to get deposite those money in bank but money didnt get deposited even after 10 to 15 days. Somethings about an app are good but somethings are not good about this app. So I dislikes this app.
