Security notice

Earlier this afternoon, during alterations to our administrator code, access to certain administrator controls was incorrectly exposed for 40 minutes.  This was immediately corrected after coming to our attention, and we proceeded to audit our access logs.

27 registered email addresses were exposed (those accounts have now been contacted), and 1 account had data altered that was immediately restored.  No other accounts were affected, no passwords are stored in plain text, and all data is backed-up and journalled.

Obviously, the privacy, reliability, and integrity of your data is our single most important responsibility.  We screwed up today, and we cannot possibly express our remorse.  While we are taking further measures to make sure nothing like this can happen again, please know that your data integrity is already our single biggest consideration.

If there’s anything we can explain or clarify, you can reach us at

We’d also like to make a special apology to Julia Allison, whose account was temporarily affected by our mistake.

  5. Just read about this on Techcrunch. Glad you guys are quick. Makes me wonder, is there a way to backup your Tumblr entries or are you just SOL if things go terribly wrong?

  6. Thats right peter, shoot the messenger.

    Its tumblr that screwed up

  7. Privacy? funny, all that the scamers have to do is read our logs. :-) Most are usually just short of including social security numbers, but barely.

  56. In the interests of transparency why don’t you explain what happened to the peoples blogs who were exposed.

    I was on Julia Allison’s blog yesterday and it had been hacked with a disgusting picture of a man’s ass, a javascript popup that said ‘I hate n*ggers’ and the browser window kept replicating. What is that all about?, how do we know that it won’t happen to us?

  58. Quick response, guys, but should we thank anyone for giving the queen of narcissism, Julia Allison, more space for her bubbleheaded brand of self-promotion?

  59. You guys are so honest. I have no doubt that all of us Tumblr users are in very good hands.
