How to remove your MLB.com account
If you want to close your Website account and have us delete the personal information in it (except for information that we keep for record-keeping purposes), you should call MLB.com Customer Service at 866-800-1275.
So sadly, your account never really gets removed. We suggest you use the aforementioned number to complain!
Helpful Trick: Obfuscate your profile info.
Because most accounts and profiles at MLB.com 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.
