One of the reasons you have gotten that idea that the forum has taken a strong stance against pligarizers and other rule breakers it's cause of the multiple appeals we see daily, it would also serve as a deterrent to others users, a sort of public execution to show the repercussions for breaking forum rules.

I support removing the email part of it truly is non functioning.
It costs moderators nothing to reply to a user with the reason, as some sometimes claim to be oblivious of what or where the copy pasted.
But everyone has a right to appeal, the fact that one user has won such an appeal shows that though rarely there can be flaws, and it would be unfair to the next one user among the thousands.
