Perhaps the TRU Score is not the "perfect" solution, but I think it's far better than a simple star rating. How many times on HN do we see posts about people "buying" ratings or followers. As a result, people lose trust in the value of the rating system. So, we have created an alternative that we think people can trust.
A future release has planned to use Stripe Identity. Whereby, you will have confidence in the profile you are viewing and can make an informed buying decision. As designed, manipulation of the TRU Score [when combined with Identity], will be difficult.
SELLFF offers multiple ways to support other members. You can write a review and go into details of your connection with another member. Buying shares of another member is an additional, low-friction way to show support. It's fast, easy and provides the added benefit that your investment might increase in value. Any investments you make are an input to your TRU Score. So, if you make good investments in other members your TRU Score will increase...even if your profile shares are not being traded.
