same here, I highly believe my App's feature set is unique but still get the 4.3 spam rejection. Really have no idea how the review works, and they never give reason but copy of 4.3 guidline. Also no reply from the appeal.

I submitted 4 appeals in 1 month, they never reply.
the reason I did it because they’re review keep saying my app has same feature sets as others and I can not find any in the App Store.
