How to remove your FictionPress account
You cannot delete your account and the admins won’t help you out either.
For some funny suggestions to get the admins to delete it for you, read this thread: http://www.fictionpress.com/topic/262/3834/Help
Anyway, you’d better obfuscate your account. Read the tip below.
Helpful Trick: Obfuscate your profile info.
Because most accounts and profiles at FictionPress cannot be removed, we suggest you login and change your account and profile information altogether.
Make sure you are logged in to your account on the site and click on the profile or options settings. Locate the fields with your personal info (email, name, address) and fill in generic, random information instead. If you can only select from several fields, change anything personally identifying. If possible, use a homepage/URL field or long text field (such as Description) and put this line in it: http://remove.org/removal-requested. This may encourage webmasters and admins to create an easier removal outlet.
