Facebook has determined that you were sending messages at a rate that is likely to be abusive. Note that these blocks can last anywhere from a few hours to a few days. Unfortunately, we cannot lift the block for you.

When you are allowed to resume sending messages, keep in mind that it’s possible to run into a block based on how many messages you send and how fast you send them. It’s also possible to be blocked when either starting a new message thread or replying to a message. Lastly, deleting old messages will not allow you to send more messages. In the future, please proceed with caution to avoid hitting the limit again. Please be aware that further abuse of such features can result in your account being permanently disabled. 

SOLUTION (ITS A FACEBOOK HACK)

>>>>>>>Deactivate your Account and Then Login Again After Few Hours <<<<<<<

 How do I deactivate my account?

To deactivate your account, navigate to the "Settings" tab on the Account Settings page. Deactivation will remove your profile and content associated with your account from Facebook. In addition, users will not be able to search for you or view any of your information.
 

If you’d like to come back to Facebook anytime after you’ve deactivated your account, you can reactivate your account by logging in with your email and password. Your profile will be restored in its entirety (friends, photos, interests, etc.). Remember that you will need to have access to the login email address on the account in order to reactivate it
