Random suggestion, would it be worth having a untranslated tag (or something similar)?
translation_request at the moment seems less like a request and more of a dump for anything untranslated.
Feel like translation_request should be best left for stuff people actually want translated, rather than just everything (Quick example would be the text on the star of hong_meiling's hat , odd bits of sfx, or random artist info)
There is also case of translation_request sometimes being removed from posts when they only contain sfx (Without actually being translated).
