!WITH PROPER CREDENTIALS THIS WILL ERASE ALL POSTS FROM THE GIVEN TUMBLR BLOG!

Use with caution and make sure you know what you're doing. That said this is 
probably the easiest way to delete all of your posts if you have thousands of 
posts. If you have less than that it might be easier for you to just use the 
mass editor in the Tumblr UI.

This requires you to get an API key from Tumblr and request xAuth access to 
be enabled.
