I deleted my Tumblr account 3 months ago so I hid my Tumblr scripts for a week, but because these ones are my only popular scripts, I unhidden the most popular ones. I just have no Tumblr account to test these on when they eventually break due to Tumblr changes.
Tumblr changes for Greasemonkey are too volatile. I moved to a Wordpress.
Update: For identification vanities this is my new blog: http://jakeis.com/ Though there isn't much for scripts there yet. I'm just letting you know again I've deleted my Tumblr, but i do have a new unused Tumblr blog to occasionally test my more popular Tumblr scripts with if they break.
