Tumblr - Dashboard Like Automator Program

I'm looking for someone who can write me a simple program to browse all of the recent post pages and place a "like" rating on all posts made by the people I am following by Tumblr. I want a program that will go page by page and place a "like" rating on each of the ten items per page and then move on to the next page and do the same and so on and so. I'd prefer that this program run on both Windows and Mac if possbible.
