Do your Part: These are just user-to-user forms. Apple barely reads the forums as it is on their own time and will. Apple will know nothing of this concern, if you do not spread the word to them. So, report it to Apple. They wont get back to you directly, but the more they hear about this, the more likely they will look into, knowing what is going on. They will know knowing of this fix, if you don't report it to them.
