Tip: prevent anonymous users without IP to answer or comment

Question

Just a tip for you, in case you have a troll like I have in my forum that visits you without IP address - and you in general allow guests to answer/comment. In other words: He can always interact with your forum --- but not anymore with this:

You can remove the answer-comment-buttons by this code in your advanced theme (qa-theme.php):

    // prevent anonymous users without IP to answer or comment, allow on ask page
    public function form_buttons($form, $columns)
    {
        $isaskpage = ($this->template == 'ask');
        $userid = qa_get_logged_in_userid();
        $userip = qa_remote_ip_address();
        if($isaskpage || !empty($userip) || !empty($userid))
        {
            // call default method output
            qa_html_theme_base::form_buttons($form, $columns);
        }
    }
    

This feature is also part of the premium stop spam plugin.

Regards,
Kai

The weird thing, it does not seem to work in all cases. "createip" is null in the database, but the anonymous guest was able to answer! ... Issue reported: http://www.question2answer.org/qa/51184
