I don’t know about this site, and I agree its unethical. But it does make me realize that I much prefer using language of the paper directly as opposed to having a non-expert poorly translate what your paper said. Especially given how papers put a lot of time in the accuracy and specificity of their language and word choices.

Would it also annoy you if they screwed up the interpretation of what you wrote? Is the alternative less reach of your work? For hard core research the tradeoffs are tougher it seems. If it is just a matter of non-nevermind, thats strictly messed up.
