No doubt, some feedbacks are controversial but DT has a long history of that. Like Lauda, marlboroza, TMAN or many more. All of them good DT members and beneficial for the community but yes, controversial.
As a correction, Lauda isn't DT and hasn't consistently been DT since March 2020 - ignoring the few "lucky" weeks here and there - prior to leaving the forum 7 months later. She was kicked off DT long before leaving the forum, in case there was any doubt.
In addition, my list was more meant like an overview of controversial DT members, I guess every case will be different from each other.
I can add OgNasty in my list as well, because despite many controversies, he's still one of the most trusted DT members. So, I wasn't planning to publish a dissertation on that issue.
In summary, Lauda isn't a good example of controversial DT members, but more so an example of how you can go from one of the most trusted DT members (+30) to least trusted (-10) within a year, which is an impressive turnaround. Lauda remains the greatest example of how not to act when you are on DT if you want your feedback to remain trusted by default.
For most of the time, Lauda was a DT member until (as I remember correctly), Lauda was distrusted heavily in June 2019. DefaultTrust (Marketplace Trust) existed since 2013, with Lauda first time on DT probably around 2014 / 2015. Therefore, I've added Lauda to my list. Maybe not a perfect example considering how it ended but until 2019 it's a good example.
But as I've said, I wasn't going to publish a dissertation about how cases are similar and where are the differences. We can probably add some more members in the list and the members mentioned in my list were just the ones coming to my mind when thinking about historically important DT members who have been very controversial while being on DT for a very long time. Because it takes a massive wrongdoing to remove a DT member who has left thousands of accurate feedbacks.
I'm otherwise not intending to compare Lauda and JG here, as they are considerably different. JG has removed or amended feedback after criticism, which is something Lauda would never do. Just thought I'd provide some context regarding Lauda since you bought her up as a "good DT member", which couldn't be further from the truth, at least based on the raw data available regarding DT inclusion/exclusion.
That's true, I wouldn't compare JollyGood to Lauda as well, the only thing I wanted to point out is: DT has always been controversial and as we've seen from other cases, where JollyGood is involved, JollyGood also listens to community feedback to solve issues, which is a very important point in my opinion.
