subscription issue

[Rudra Banerjee]

Hello,
I am a subscriber of this list, but there is no post delevered in my
account. I also get a automake bounce notice, as 
"Your membership in the mailing list Automake has been disabled due to
excessive bounces ..."
I tried to reply the mail as directed on the same day, but got:
"- Results:
    Invalid confirmation string.  Note that confirmation strings expire"

Is it possible to delete my account and recreate it? I tried to delete,
and failed.
