If you are a merchant and spend a lot of time on images it might be worth blocking them since pinterest is quite literally stealing your images
There are may be valid reasons to block pinterest in some cases, but it is really sad if the times has come that webmasters will block pinterest because of potential impact on Google rankings. If that happens then the internet is seriously broken. Broken by Google. I am not saying Google is so stupid as to punish for pinterest links, they are probably not, but their intimidation campaign is causing a lot of damage.
