In my search for free Tumblr bots I came across this little gem. http://www.supagrowth.com/Expired-Tumblr-Hunter It's of no use to me personally as I use scrapebox, but for a noob or someone that can't afford SB it's awesome. It finds expired Tumblrs and you don't even need proxies and it's totally free, small download, and simple to use. Only minus is it doesn't work on my beloved win XP ;-( I tested it on win7works cool, bit slow though compared to SB. There's also 12 other free programs on the site, all free, no adware as far as I can tell.
