• You cannot join tumblr if you are under 13. Even if you are 12.9 you should go read a book or play Xbox until you’re 13 (lol I joined when I was 12)
• You can’t tag stuff completely irrelevant tags, like tagging a photo of the TARDIS as “Lady Gaga”
• Here’s the big one: No more non-recovery oriented self harm blogs, no more pro-anorexia or pro-bulimia blogs.
• 
  No bring a total dick. (seriously it’s there)
• NO MORE FOLLOW TRAINS OR PROMOTING YOUR BLOG UNDER EVERY POST. A follow train would only be permitted if it was like “Here’s some Supernatural blogs to check out if you want! Add your URL if you post Supernatural!” Not like the ones that are just follows for follows.
• No hoarding or collecting of URLs. So no reserving…
• No extreme hate or encouragment of violence against a particular group (ike, Hitler style “KILL THEM ALL” not “Let’s assassinate Rick Santorum and Sera Gamble”

That’s basically all the important stuff.

You’re welcome! :D
