I was recently banned from a sub for attempting to subvert a Google bomb. The subversion technique I was attempting was to wait for a grass roots Google bomb to form then add a comment containing a link to a picture they would not want associated with the Google bombed phrase. A variant of this would be to post an innocuous comment then go back after the thread has died down, but still in Google's view and edit the comment to include the subversive link. Another variation would be to flood the comment with OK links and hide some subversive ones in the noise.
Does Reddit have a site wide policy on Google bombs?
