Hey, I have been experimenting with Expired Tumblrs for the past 3-4 months now, my strongest position so far have been #8, but the 23th June I started building 3-4 Tumblrs per day, which I didn't do to begin with. Further down the pages you can see the type of links I've made and date I made them. The majority of the links are Tumblrs, I also have a couple of Wordpress, 1 Blogspot, 1 Weebly, 1 Bravesites and a few profile links. If anyone got some input that could help me get a better ranking, then I would appreciate it.
Progress: (Unfortunately you can't see the big jump, because I tried moving this site into a new campaign, which wiped its history. So this one looks like the Tumblrs didn't do much, but I reckon I have been around 50-60 to begin with.)
Links and date I made them on:
