Reputation is a very important problem worth solving. However, I'm not sure your app tackles the most important part of this problem, which is connections between participants. For example, let's say I started a business and I need first customers, which I cannot get without the reputation. One cheat is to simply create 100 accounts on your website, each referring to each other and giving points to each other. Even if you manually check each account, which I think you wouldn't be able to do at a certain point, I can game the system and gain fake reputation. An alternative would be a system based on connections. For instance, if my friend or a friend of my friend gave your account some points, then I can be more sure of the validity of your reputation. The more connections you have to me and the shorter the route, the more reputable you appear to me. On the other hand, if all your points come from your own fake accounts which have no connections to any of my friends, your reputation appears 0 to me, even though you have 100 points.
