I kind of do it but more to learn a bit more about the language(have rudimentary knowledge of both Chinese and Japanese, don't recognize enough characters to even pretend to translate lol) and to rewrite it to something I don't mind reading in the future. Obviously 0 plans on releasing it to the public, but it's kind of nice to know that a few years down the road, all that mtl bullshit you waded through? resulted in something you don't mind reading yourself if you like the story enough.
If it's something I don't feel like rereading in the future, then I just drop trying to "failtranslate" it. No harm done to anyone in the end. except my brain cells
