You highlighted a big reason why the DT system is struggling.
Politics. You can have two people with the same morals and same hatred of scammers, but one little cultural slight or misread of a post and BOOM - they are now fighting with each other.
I'm not sure how the system can be changed for the better without letting the multiple account Quickscammer take over. :/
Unfortunately, I think it will take other DT1 members being attacked the way I was and deciding that they are ok getting hit with a little red in order to be part of the solution instead of the problem. DT1 members expanding their trust networks to include more trusted longterm members who haven't engaged in shady behavior is a start.
