How to remove your Craigslist account
Deleting accounts? CL seems not to have heard about it. Besides, in the PP they name the retention of all kinds of data. Anyway, try and request removal here: http://sfbay.craigslist.org/feedback – you may want to delete your contributions first and/or obfuscate your data. Noticing the retention, that is what you may want to try – depending on how much you value the contributions regarding privacy.
Helpful Trick: Obfuscate your profile info.
Because most accounts and profiles at Craigslist 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.
