Thanks for your help (and for yours, @DollyDaydream), but sigh I guess I need to say it again - Wanikani seems to be really strict about not-exactly-legal-content. I’ve seen it in other threads and I feel responsible for monitoring this one. I realize you can find some things very easily anyway, and that other places may be not that strict, but I didn’t make Wanikani rules.
In this thread, for example, it’s explicitly mentioned that moderators really do care about this policy being respected.
