I can fully understand this ban by the US Marines. The security of Facebook leaves a lot to be desired. It is extremely easy for hackers to access users’ profiles and request money from people under false pretences. Facebook are aware of this problem, yet they have so far failed to provide any meaningful solution other than resetting the user’s password. If the hacker wished to gain access again, it would not be a problem. A password is not going to stop them, no matter how strong it is.
I know first hand of Facebook’s incompetence. When a profile is hacked, Facebook fail to react until after the 2nd or 3rd report by the user. During this time, the fraudster is continuing in their attempt to extort money from other people.
The hacker is capable of very quickly accessing a user’s profile and changing the email address and password associated with the account. This effectively locks the user out of their account. Due to the length of time it takes Facebook to stop the hacker, the hacker has time to contact all of the user’s contacts to request money no matter how many contacts there are.
