Deleted all my tumblr posts. lol All 8k + of them 

(before you ask, go to your dashboard, click on your post count. just below that is mass editor.

Put this script in the browser and it will auto select 100 posts, which is the max Tumblr will allow to be deleted at once: 

javascript:$(’.overlay’).slice(0, 100).click()

If your browser erases javascript: at the beginning, just retype that shit

hit delete at the top right. Repeat until done. And yes you have to keep putting that script in your browser thing).

You’re welcome.
