Can those Credit Systems be it China’s or any social networking services be gamed? I’ve seen a lot of people deleting their accounts out of fear for their data and privacy. But at the same time, a lot people get the system to work in their favor, e.g r/churning. I’m not dismissing the harm or discouraging conversation for privacy. Just asking if we can hack it.
