Negative trust feedback from DT members does not necessarily mean that the account is complete "wasted", especially if you mean that account can't participate in any signature campaign after red tag. I see many members who have many positive (green trust) and one negative (DT red trust), and they still generally have the status of a good member on the forum.


Escrow is not good only because of trust, but also for reason that trade can go bad in case the seller/buyer experienced an accident before it fulfills its obligation. In case the funds are escrowed (and escrow is an honest person) security is guaranteed.
