You can also try sending an email to [[email protected]] to ask why your account was disabled, as well as explaining that you are willing to remove any offending content in order to get your account reinstated.
Facebook's help section is also available even if you cannot log into Facebook. This section looks into various warnings and reasons why your account may have been disabled.
Securing Your Account
You might want to secure your account even if it hasn't been disabled by using this wizard.
WARNING: starting the wizard will IMMEDIATELY lock out your Facebook account and you will be forced to change your password and go through several additional security measures, such as confirming that you've changed your email passwords.
We also advise regularly backing up your Facebook profile (we explain how in this guide). That way, even if disaster happens, at least you have a backup of all your data on your home computer.
For a detailed description of the steps you can take to make your Facebook account more safe and your information more private, check out our guide here.
