My account has been suspended on SO. I request moderators to close or delete my account. I want a new fresh start.
To request deletion, use the "contact us" link at the bottom of every page on the site (SO, not here on Meta), or reply to the suspension message.
Don't plan to get that fresh start during the period of your suspension, though -- that would be evading a suspension, and is grounds for suspension or deletion of the new account. If you've been suspended, just wait it out.
Since you're waiting anyway, you might as well keep your account and come back when the suspension is over. It's only a week.
