Digg makes it very hard to delete your account, searching the settings page option leads to no avail and searching for it on Digg leads to submissions from users who wish to delete their account.
Fortunately, account deletions are allowed, however, users must dig deeper (pardon the pun) to find the frequently asked questions page, which includes information on deleting an account under the heading “How can I close my Digg account?”. Here are the steps to delete you account forever (correct on date of publication):
- Contact Digg support, using the form or email (firstname.lastname@example.org)
- Include your Digg username and state the reason for deletion
- You should receive an email from Digg support confirming the closure of your account.
