Having used Jack's Imacros script to save a lot of time following people (although it now seems that whilst i used to get around 33% of those i followed follow me back, its now 0%, yet i can still follow 200 people a day, so not sure whether ive been sussed by tumblr!) I thought i'd play around with imacros to automate a few more tasks. The first.... you just go to whatever page of tagged postsyou like, set the amount of loops, and it'll like them all, no need to scroll down the page to load more posts, it does that for you! I've got fast internet so can like about 500 posts in a minute with this! The second script is to unfollow those that don't follow you back (having used Jack's script, i basically had 2,000 people i was following that didnt follow me back) SO, to use this, load firefox, and install xkit extension for tumblr once you have that, there'll be a new button on the right side of your blog dashboard that lets you see who you are following, but which of them does not follow you back. Wait for the list to load, then run this macro The screen will go a bit mad and keep flashing up and down.... but it gets the job done! You just need to wait a while for all of the unfollows to process after the script has finnished looping.
