The significant benefit is that he tags scammers and helps keep that under control. Will he sometimes mess up with a rating?? most likely, but if/when he does he just needs to make it right. The trust system is not perfect, but no one can come up with a better one so it is what it is. Obviously other members of DT1 agree he is valuable otherwise he would not be back on.
I'm not disagreeing with you, I was just saying your criteria may have been carelessly worded. I know Lauda presents a clear benefit to the community, but I also can see why people are concerned for them to remain in a position of responsibility. They give people multiple chances and operate fairly from what I can tell; some are offended by their callousness, but this is not something I am concerned about.
I don't have enough information about Lauda specifically to have a stance, but I was simply saying that your criteria was weak and unsatisfying, in the manner it was presented/explained.
