Yep, there is a nasty little trend of textbooks whose homework assignments require a code for a publisher site. The student is then required to fill out the answers on that site. It mostly happens in lower level classes. Why grade students when the computer will do most of the work?

On a side note, I saw a video of some professor ticked off that students got a hold of a test battery from a publisher. This "get all the questions from the publisher" makes me think these folks don't want to put any effort into the class. What is the difference between a prestigious university and a community college given that level of effort?
