Just remove those people from the DT member system. Like how Lauda left the forum, his feedback can be replaced by other.
But if the no longer valid feedback just gets replaced by another invalid feedback, nothing changes. The problem didn't go away.
No, that's not what I mean. The DT members can replace the feedback with other feeback. But only really useful feedback was replaced. Feedback similar to those listed above should be ignored. I take the example of TMAN, we can replace all his feedback by other DT, except for the feedback on BestChange account. Since you commented on TMAN's inappropriate feedback, I think it's the best one to remove.
But if TMAN and others are excluded, those that are included by TMAN will be at a disadvantage. I think that's not a good thing, they won't want TMAN to be excluded, maybe
