Not accepting escrow and asking the other person go first often earns the member a negative rating. It doesn't prove that the person is a scammer though and I've often been voicing my opinion about that as I did the same when I was new here.
There's a big difference between refusing to use escrow and forgetting to mention escrow. I also wouldn't send first to a newbie without escrow.
As we know, Quickseller runs an escrow service and makes money by neg-repping others and not looking back. We've yet to see an instance where Quickseller admits he was wrong unless there was absolute concrete proof he was wrong (see the case of ndnhc). He's quick on the trigger, so to speak, because that's what gets him to the top.
The problem is that there's no accountability for his false-accusations. People with lower-ranked accounts will just move on and get a new account, maybe they'll even buy one from him (conflict of interest!?). He can slash-and-burn his way through the lending section, dropping red trust and not looking back. People who were caught in his cross-fire have no recourse and people who aren't caught in his cross-fire think he's somehow doing a service.
This is the problem with the trust-rangers, the people who are trying to consolidate power by dropping as many red-trusts as possible. There's no accountablilty for their actions. Either they were right, in which case people say "good job", or they were wrong, in which case the poor newbie just says "what the fuck" and makes a new account. There are almost no people willing to stand up for themselves because of situations like my case which prove that QS can stand for 6 months dropping false accusations. They see that he'll use sock-puppets and lies to knock you down and they don't have the stamina to fight back. Mods can look in my PMs and see the many supportive messages saying they feel bad for what QS is doing to me but they won't speak up for fear of crossing him.
I don't know what this guy was actually trying to do and crucially, neither does Quickseller. The difference between him and me is that I'm not a trust-ranger/account-seller/escrow provider, so I have no vested interested in neg-repping newbie accounts. If QS was actually trying to make a difference for good on the forum and not just puff himself up, he would have simply posted in the thread that PP is suspicious and debit-card should use an escrow. That would have been enough to get the message out but it wouldn't have inflated his neg-rep count, which is how he's working his way to the top around here, and the blood of many of us peasants is running in the rivers as he kills his way to get there.
The difference between Quickseller and other DT members is that others will apologize and remove the negative rating if there's been a misunderstanding or a miscommunication. We've yet to see QS do that.
