LOL. It looks like that I started a hot topic, that might long-last over weeks or months. 
To be honest with you all, I don't really care about Trust system, because it is too complicated to me.
Of course, for someone who are famous, reliable in the forum, with or without Trustscore, they will always be well-known.
Trustscore is only make sense when I see some accounts the first time, I don't know who are they, how about their reliablity.
In such cases, Trust score makes lots of sense.
