I got Banned from Digg?

My major concern is the reason behind taking such a harsh decision and disabling my digg account permanently. I got the mail from digg people that I have been banned because I did some prohibited submission. I really don't know what exactly they are pointing to.. and they just left with a note as their decision is final and irreversible. But I am really curious to know exactly what I did??? My digg submissions can be tracked here http://digg.com/users/skewl/history/s...

So please, can I appeal to the concerned authorities and other people around there to look into this matter and let me know exactly why it was done to me and what are the next steps I need to take to get my account back. I'll really appreciate any help on this matter. Please guys, do respond!!
