How to delete my private data?

To whom it may concern,

My account was banned on November 13, 2006.

I still show up in the "birthday" section.

Since I am not an active user and my ban is permanent, I suppose I can't hide the private info from my registration myself.

I would appreciate it if you could delete my personal data, including my birth date.

Thank you for understanding.

I went ahead and turned off the visibility on that data point.
