The root cause of this problem will be solved if merit sources stop distributing so much merit for translation and are more selective when accepting someone's request for translation. Some newbies want to rank up and they want to do that fast. They look for possible way from where they can get a lot of merit. Perhaps if we could give a recognition badge to all the skilled translators that could be enough as a reward.
Unfortunately, theymos won't patch the forum just to include the translator badge. A translation needs a lot of effort to do it. So, awarding translations is not bad. The problem is, that the authors do not have a way to judge the quality of translations unless someone from that local helps.
It is good that you guys pointed out the bad translations and the author also looked into it as 1miau already said, he will ask us or other native speakers to check the translation before he rearwards. The matter is kind of solved now. So DVlog brother, I suggest you to lock this thread to avoid repeated discussion of same thing that we already discussed.
