For my very own experience with a Lauda feedback, I would say there is a very good chance Lauda made adjustments before he ceased to exist in the Lauda form, or maybe I just got lucky that he kind-heartedly reconsidered adjusting his feedback to me.
It is possible that he/she went over some of the ratings that were handed out and revised those that were no longer valid or deserved to be altered. I do remember when a member from the local Croatian board (RegulusHr) got banned for plagiarism that Lauda tagged him for stealing content.
More than a year passed before RegulusHr was forgiven and got unbanned. Before he did, Lauda deleted her feedback.
Correct. I have changed my mind and removed my rating when I have seen other cases that were unbanned. RegulusHr is an extraordinary member when compared to those.
In any case, Lauda is not on DT anymore and her ratings aren't the problem here.
