This is definitely well outside what trust is intended to do. I wouldn't hold my breath for this to be changed, so your only other recourse is to PM anyone who has them on their trusted list that you think will objectively look at whether or not they still do more harm than good, when DT.
Different high-ranked users came up with guides such as "In which case it is appropriate to leave a negative feedback" for other users.
That may be but there are still guidelines in place whether people like it or not. Ignoring when someone blatantly disregards them degrades the entire system especially if it's only because they have a high profile/ high ranked account.
