What addon is this?

I found a forum that uses a post ratings feature that let's you give different ratings for a post and it tracks your ratings under your name.

See this screenshot: http://i.imgur.com/jckzUuF.png (see in the far bottom right for the different icons/post ratings you can do)

Under your name is the amount of ratings you have been given.

I've seen a few post ratings, but none exactly like this one, is this custom or am I just not finding it?
