Recently there was a [blog post](http://www.redbubble.com/people/redbubble/journ...) that went out that you may be interested in reading through. Basically you can easily remove the “Pin it” button by heading over to your [Account Settings](https://www.redbubble.com/account/settings), scrolling to the bottom, clicking the relevant “Hide the Pin it” box and saving your settings.
