I often come across half-finished collections where the previous translator has gone through and translated only the list items and bullet points, for example. Other times they will purposely avoid any items containing unit conversions. I feel like this kind of behavior should be discouraged, perhaps a penalty for dropping too many jobs in a certain period of time? I understand that those jobs will be marked up if they sit in the queue for too long, but knowing I'm doing the hard part of someone else's job is frustrating.
