I've been scraping inactive Tumblr blogs with scrapebox for the past few days. I've got 10 x PR1 10 x PR2 and 1 x PR3 so far. I've been using the following method which I found somewhere on here... 1) Get a keyword list, or scrape one with Scrapebox 2) Use footprint site:tumblr.com/post/ 3) Scrape 4) Trim to root 5) De-Duplicate 6) Run results through vanity checker addon 7) Export available blogs 8) Check PR 9) Register blogs with PR1+ Now if you have done this you will have noticed Tumblr's standard 404 page. It has the same little bit of text every time... There's nothing here. Whatever you were looking for doesn't currently exist at this address. Unless you were looking for this error page, in which case: Congrats! You totally found it. So, just as you would use the following footprint to search for Wordpress comments: site:.edu "You can leave a response, or trackback" Can we not use: site:tumblr.com "There's nothing here" Or a footprint with any other part of the standard text on their 404 page. I've tried it and it didn't just return available blogs so I'm either dumb, missing something, unlucky, or all three.
