You know they have killed your Facebook account despite all your efforts to restore it when you get the following message:
Facebook has limits in place to prevent behavior that other users may find annoying or abusive. These limits restrict the rate at which you can use certain features on the site. Unfortunately, we cannot provide you with the specific rates that have been deemed abusive.
Your account has been disabled because you exceeded Facebook's limits on multiple occasions when sending friend requests, despite having been warned to slow down.
After further review of your account, we have determined that you violated our Terms of Use. We will not be able to reactivate your account for any reason. This decision is final.
Thanks for your understanding,
Marissa
User Operations
And then:
I apologize for any inconvenience but unfortunately, as stated in the previous email, I won't be able to reactivate your account since you have violated Facebook's Terms of Use many times. Your cooperation and understanding of our security policy is very much appreciated.
Thanks,
Marissa
