I have done some 200 jobs for Gengo and never did my review drop below 9.3.
Then I got this very small job which came with specific instructions, namely "if you have any personal suggestions, or that you have to change a word to make more sense in the target language, please don’t ask for permission, you are free to do those changes".
I changed ONE word which I thought sounded better in Hebrew, and for that the reviewer "corrected" me (with another word, which is also not an exact translation and sounds less natural than the word I chose),
and for that the reviewer gave me an outrageous score of 3.03 \ 10.00 !
I find that unacceptable and insulting. Now my overall rating dropped to 7.3 !!
I asked for a re-review and got NO answer at all.
