Just got that mail... that sounds like a great thing, and i will be sure to use it when i get a chance.
But what bugs me: how do you plan to deal with the people who would hire themselves to gain success score, opening fake accounts of clients? It will be so cheap to do so (just some foreign exchange commissions, or maybe not even that when using U.S. payment methods) that it will be tempting to do so. Won't we soon face a whole new brand of fakes?
What i suggest: don't include contracts with these 0% clients into JSS calculation, top rated/rising talent, and otherwise take means to make sure they don't help a profile stand out.
Thank you for the feedback, i will share it with our team.
And about the first part when we discover someone had opened a client account so that he can boost up his freelancing score we take proper actions against them.
If you get suspicious of this activity please report them, and one of our team will have a closer look.
