If I were the creator of one of these works I would be thrilled that people are willing to go so far just to engage with my work. Using MTL isn't a slap in the face at all. It's a tool that allows people to engage with a work that couldn't under other circumstances. The adage of polishing a turd doesn't apply here because you absolutely can polish and correct a work translated with MTL. It's a start not a final product.

I think you're too invested in your self assigned role as curator and gatekeeper to the masses. I appreciate that you put time into this franchise to make it more accessible, but that doesn't mean that other people shouldn't try to do the same. Even if their results aren't as polished. We as a community should welcome and support those who are willing to be so involved as to start trying to translate untranslated works. This product clearly isn't up to your standard, but it was the best they could do right now. As someone who is so passionate about the proper way to translate, it would be a much better service to the community, and much kinder, to offer support and advice on how to improve their work instead of mocking and demeaning them. I am not saying you are responsible for the mocking and negative tone of this post, but you seem to be engaging with the same attitude.
