ResponseSource's nofollow policy
Why add nofollow tags?
This is in line with Google guidelines on the way it perceives links on press release wire services.
On Google’s Webmaster Tools Link schemes page it provides general guidance on links that 'pass PageRank' (put simply, passing PageRank describes how Google’s perceived value of a site is influenced by the value of a site that links to it). Among other things, Google states "links with optimized anchor text in articles or press releases distributed on other sites" may be considered as "unnatural links" and therefore a violation of Google’s guidelines.
By having nofollow on links, ResponseSource complies with Google’s approved method of linking within press releases.
