Way to report facebook
There are many different issues which can arise on Facebook like imposter profiles, being locked out of your account, being tagged in photos you didn’t want to be posted, abusive messages on your page or about you on someone else’s page.

The most common query we have from Facebook users and educators is how to report and/or block a fake profile.

You can report a profile that violates Facebook’s Statement of Rights and Responsibilities by clicking the “Report/Block this Person” link in the bottom left column of the profile, usually underneath the list of friends.

The most important part of these terms of use is buried in Section 3 – Safety: “You will not bully, intimidate, or harass any user”.

Facebook say that reports of offensive material will be responded to and the target informed of the steps that will be taken against the offender within 72 hours. In our experience it can take anywhere between 1 hour and several weeks for profiles to be removed but it helps if you ask friends to also report a profile and choose carefully from the options listed on the form.
