My site (http://seattlerueda.com) has been injected with links that are only visible to search engines - clearly for SERP improvement. See image from google's cache :
The hack is clever in that when I use agent switcher in my browser the version sent to the browser has none of the links. Since I cannot recreate it, it's hard to track it down through the code. I am running 3.3.2.
Has anyone heard/seen this and have ideas where to find the rogue code ?
