I just sent a message through a general app questions in iTunesConnect... does anyone know of a specific Apple e-mail address for these kinds of issues?
try AppStoreNotices@apple.com
that's where all of my C&Ds have come from :)
If Apple follows the DMCA (and I'm sure they do), they must publish an official address at which copyright violations can be sent. So you shouldn't have to guess how/where to reach them.
