Xenforo Addon to show hidden content for SEO

My XenForo forum currently has several private areas which are only available to members who have x amount of posts, and have been a member for x amount of days. Here is what I would like the add-on to do: *Show thread titles to members *Show the first post of threads when clicked on *Hide all usernames of members on all pages for the related sections(instead of the username, simply display "unavailable" or something similar). *Be able to select which forums this applies to in Admin CP *Be able to select which user groups this applies to in Admin CP(unregistered users) *Blur out/hide any additional posts and display a text box with customizable html text *Should be a full add-on package that is able to be installed and uninstalled Thank You,
