This latest issue with Dt1 members being caught red handed lying to the forum and using trust inclusions and PMs telling people they have sent money to collude with them to prevent flags for companies they shill for is disgusting.
DT polices itself, and I'm familiar with the issue you're referring to. Last I checked, there wasn't strong evidence that the above actually happened the way you described it. If more facts come to light about it and there's some shenanigans uncovered, that member will likely be voted out of DT.
DT1 should consist of elder members than can sign btc wallets containing 100 BTC minimum that are never touched. They should also have no affinity or sponsorship from any company. They should have been here since 2012 or 2014 minimum.
They must have zero occasions of any financially dangerous actions in the entire history.
If DT had standards of inclusion like that, you'd probably wind up with a list of members who aren't active anymore, and the net result would be a useless system. The trust system is very far from perfect, but unless Theymos does a major overhaul we've all just got to deal with it the way it is. My guess is that he's probably made all the changes he's going to make for a while.
