What measures can be taken to prevent new users from using a PHP forum for unrelated discussions?

To prevent new users from using a PHP forum for unrelated discussions, you can implement a user role system where new users are restricted from creating new threads or topics until they have reached a certain level of participation or have been approved by a moderator. 

// Check if user is allowed to create new threads
function can_user_create_thread($user_id) {
    $user_role = get_user_role($user_id);
    
    if ($user_role == 'new_user') {
        return false;
    }
    
    return true;
}

// Function to get user role
function get_user_role($user_id) {
    // Code to retrieve user role from database
    return 'new_user'; // Default role for new users
}
