NoFollow
Recently, Google announced a way to combat comment spam using rel="nofollow" in link tags. When the google bot finds this snippet, the bot will not follow the link. The idea is to remove the reward from comment spam. This module will transform any links to add this snippet to the links.
Install -- Unpack the nofollow tar to your modules directory. Go to your modules admin and regenerate and install nofollow into Xaraya. You will want to hook the nofollow module to the comments module. Simply click on the comments hooks from the view in the modules and hook to comments module or any other module that would have direct user input.
