I can not pronounce myself about all cases mentioned in OP, as I have to admit I did not study them all. However, unfortunately,
I was forced somehow to study very well one of them. It happened against my will, as I never wanted that, yet things in life don't always happen as we want, so I was actually dragged in studying TimeLord's case -- I was dragged by his actions against me (his most recent one being the fact that he gave me a feedback calling me racist Oo -- obviously, with no
relevant reference link).
I understand that yahoo questions the feedbacks in the cases he mentioned in OP (and, perhaps, some other ones as well). However, by taking a good look at TimeLord's received feedbacks, we can see that those calling him a liar / troll are users with very good reputation on the forum. Among others, we can see the names of LoyceV, 1miau, icopress, marlboroza or nutildah. Furthermore, these feedbacks are neutral ones, so they fully respect
the rules of Marketplace Trust system.
Should we hand out neutral/neg tags like candy?(open but might be future edits)
As long as there are no financial deals involved, neutral feedbacks should be used. Sadly, not all users know that and many misuse the
Marketplace Trust system, and I am emphasizing
the official name of this system, as many consider it simply Trust system. It's not a Trust system, but
a Trust system for Marketplace. Meaning it should be used for financial deals when giving positive or negative feedbacks. However, for all other kind of feedbacks users may leave neutral feedbacks.
If someone argues with a DT member, DT members will ~ them. So, there is no point in sharing an unbiased opinion. The only good thing is, If a DT member says, "This is correct, and that is not, " I have to agree with him as an average Joe. The better decision for an average Joe is to ignore the reputation board and start shitposting to make money from the signature campaign (Which I have been doing for the last couple of days).
It's normal, so @Learn Bitcoin, don't worry. I don't know about your issue but blaming DT like how you did it, is not really accurate.
I believe that Learn Bitcoin had a bad experience with a DT user (or some DT users) and he tends to extend this view over all DT users. Or, perhaps, he is too polite and, instead of pointing the finger toward someone he talks using a general approach. I can not say anything about Learn Bitcoin's (bad) experience with DT, as I don't know it, but what I can say about him is that he translated some topics of mine and he did it in a very professional manner. He was serious, he finished the work in time and he did it well. I am thankful to him for his (free) efforts in translating my topics and I think he is a serious user.
