I want to store user ip address with $_SERVER['REMOTE_ADDR']. From what I understand, this works perfectly until user uses proxy.
I could use in those cases $_SERVER['HTTP_X_FORWARDED_FOR'], but this can be faken.
So I am thinking to deny access to publish content pages for user that uses proxy. I only need to store ip of those users who publish content.
But in which cases users use proxy? I don't want to close publish option to too many people. Is proxy used also in some public networks or companies and user even don't know that?
