Sorry, I don't know the answer. But that would be a fun job, and I have no doubt you'd be better at it than whoever's doing it now.
For instance, the description for the movie
Kingdom of Heaven. A couple of years ago, I noticed it had this description:
Netflix a couple of years ago said:
During the 12th century in the holy city of Jerusalem, a young peasant blacksmith (Orlando Bloom) takes up the mantle of knighthood so he can help repel the army of Christian crusaders that took control of the city in the year 1099.
You'll notice this is idiotic. (It includes the fact that Christian crusaders took over the city in 1099, but then scrambles the relationship between that fact and the action taking place nearly a hundred years later.)
I wrote to Netflix on the subject; sent them several dozen emails with no response. Finally got somebody on the phone, and I explained to him how to fix the description: change "Christian crusaders" to "Islamic warriors" or "Saracens", and change 1099 to 1187.
Well, they managed to make it worse. They changed exactly one word. Here's the description as it reads now:
Netflix said:

That's right. "Islamic crusaders".
