Even though our exploit is pretty generic and sophisticated, there are multiple scenarios where it fails. There are a lot of exceptions to this but to give you the main pointers, the Blue Portal Facebook password hacker generally fails if the account is either:
Not a facebook profile. We can only hack Facebook profiles, NOT Facebook pages. If you want to hack a Facebook page then you need to enter the link of the profile who is administrator of the page.
Accounts created before 2005. The graph API was not released before 2005, thus it is not implemented in those accounts.
Huge celebrities. While it might be possible, our system automatically denies profiles that are deemed as "high risk". If we started hacking accounts of presidents we'd quickly get in trouble so we have decided to avoid that. For more information visit website #facebook hack.
