The CEO of Facebook Mark Zuckerberg, is probably never going to send you a personal message. 
According to a discovery by Hoax-Slayer and reported by AllFacebook, the following message from Zurckerberg (yes they botched his name) is appearing in users’ inboxes around the world:
Mark Zurckerberg Dear Facebook user, After reviewing your page activity, it was determined that you were in violation of our Terms of service.Your account might be permanently suspended. If you think this is a mistake,please verify your account on the link below. This would indicate that your Page does not have a violation on our Terms of Service. We will immediately review your account activity,and we will notify you again via email. Verify your account at the link below: ========================================= Link Removed =========================================
Hoax-Slayer reported that the phishing scheme is designed to trick users into giving up their Facebook login details to cyber criminals. The fake message appears alarming and purports that the user’s Facebook account is in danger of being permanently deleted because of some violation of Facebook’s Terms of Service. The page owner is prompted to then click on link to verify their account and show the page is not actually in violation of the TOS. Users that fall victim to clicking on the link end up at a fake Facebook login page that closely resembles the real one but is really looking to steal the users’ login credentials.
If you receive this message, do not click on any of the links!
There have been countless variations of phishing attacks against Facebook over the recent years, so always stay alert and avoid any suspicious messages or links.
