DefaultTrust is default. No one bothers to customize their trust settings.
So when you see "Warning: Trade with extreme caution!" on their profiles, you automatically think this is a scammer. But when you look at the reasons, you see words like: shitposter, spammer, etc which I don't think means the person is dangerous to trade with!
How would you like if I label you a murderer but all you did was a traffic altercation? Totally unjust and broken is the trust system.
Because I know the politics behind the scene here. Those trust feedbacks against Quickseller is basically biased and subjective. But to a newbie, it's totally misleading. If you hate him so much, ban him.
That is their problem. the trust system has absolutely no bearing on anything outside of the marketplace sections. Who cares if a guy who is posting about the political climate in Tibet and its relation to Bitcoin's price is untrustworthy to trade with. This is a forum, as long as you aren't disruptive to discussion, you aren't banned.

Just like with feedback, you'd have to back up your claim. If you left someone feedback that said they scammed you for 100 BTC without any reference link, proof, etc, people would just disregard what you say, the same is true for Quickseller's feedback. If you don't believe whatever their feedback says, or you don't care, you are free to trade with them. I've done successful deals with scammers before, I just made sure to use escrow.
