This last week has been intense with the coding ... We are in the midst of redesigning the social scores at the moment and looking at ways to also find out when people are artificially "gamng" the system. So we are writing apps that track people's scores and their search result patterns. Just like how criminals are always tracked by looking at what they are buying - when a person that wasn't spending a lot of money starts to buy boats and high priced items, then it may be a sign that they have gamed the system and did something wrong.
Bottomline, when people see the value of the Zabang system, the first thing unscrupulous people will do is to try to figure out the hacks and how to get better scores without doing the work that deserves that score. This is not a question of if, but when. It is just part of being on the Internet. We want to make sure that when this type of thing happens, people can spot it and alert us.
