Okay, okay. I do get the encouragemet we are giving, and I also want to read this as much as the next fellow. In this short time it has become one of my most favourite manga and I always look forward to reading it, even if the translation is, indeed, quite bad. Not bad to the point where it hurts, and it's not machine translation either, but bad nonetheless.
What I want to say is that a person doing a bad job should not be encouraged to keep doing a bad job. If people are telling you that your choice of word is wrong, maybe it's actually a thing you should work on. Yes, of course we are not paying for this and thus we shouldn't have any right to complain about it ... Well, that's not how it works. If you are uploading it, you are taking some credit of it, even if no money. And if you take any credit from something, you are responsible of it's quality.
Don't get me wrong. I'm not telling you to drop this or stop translating. I'm telling you to get better at it. You are obviously not a native speaker, or if you are you have not read all that much literature. And that would be my advice: read Conan Doyle, read Clarke, read anything written in English, read a lot.
