I have no problem even if they remove whole trust system from forum because its better to have no such system then giving ipower to the guys who misuse them against forum rules
giving power to such users is like giving loaded gun to monkey, if someone doesn't have ability and take action emotionally then its same thing
if you get power you get responsibility too, but if if after getting power someone think they can do anything then its worst then giving gun to monkey
I do not think negative feedback (at least from DT) is deserved just for selling accounts unless there's an agreement/rule to forbid it or unless trusted/green accounts are being sold to untrustworthy users or other actions are made that may help scammers (which is not the case here AFAIK, let me know if I'm wrong).
Besides I think jonald_fyookball has left several undeserved negative and positive trust in the past, I've explicitly removed from my trust list a couple of months ago.
However OP you're criticizing him for acting "emotionally" and frankly you're much more guilty of that in this thread. Your generalized accusations are not helping too much. I get you must be affected by this but try and be more objective about all this.
That said maybe it's worth (re-)opening a discussion to decide whether selling accounts should be forbidden or at least not used as collateral. But until the community decides it trusted negative feedback is not deserved.
