I’m going to pretend he’s serious and we’re willing to help him as best we can without admin intervention……..
This won't delete your account, but it might help get you further towards your goal.
A) Delete all the posts that you can.

Go to each post one by one and delete. You don't have a bunch, it won't take long.
You can't delete posts of threads you started, but you can edit the thread title and post, and just put in a period or something meaningless. You also can’t delete posts in closed threads (classifieds).
B) Anonymize your profile. Remove the avatar pic and location.
C) Use an online free email anonymizer and change the email address associated with your account.
D) Go to privacy settings, uncheck everything, and set the options in the righthand corner to "Nobody".
E) Log out
That's about the best I think you can hope for. Renewals for your supporting status will go to that email and bounce in the future. If anyone looks you up in the future, there is not much left.
