I've also not noticed him thank anybody for doing his homework for
him, either, but this may be a result of me ignoring the threads before
he gets round to it.

I do like to think, though, that his tutor occasionally googles code

list and then not find yourself flooded with links to mirrors of it on
the next related google search.
