Question

Facebook has blocked my account without any notice. How can I recover my account?

Answer 1

In some cases Facebook may not issue a warning before disabling your account. Also note that Facebook don't restore accounts that were disabled for severe violations of the Facebook Community Standards.

From Help Centre:

Facebook disable accounts that don't follow the Facebook Terms. Some examples include:

• Posting content that doesn't follow the Facebook Terms
• Using a fake name
• Impersonating someone
• Continuing behavior that's not allowed on Facebook by violating our Community Standards
• Contacting other people for the purpose of harassment, advertising, promoting, dating or other conduct that's not allowed

If you think your account was disabled by mistake, please submit an appeal.
