I have seen this style of "account virus" post on Tumblr for months now. I have seen this exact post quite a few times in the past week. It's just like you see on Twitter or Facebook with people who get their accounts compromised and it auto-posts spam. You just need to change your password and/or see what apps have access ( https://www.tumblr.com/settings/applications https://www.tumblr.com/settings/applications ). Maybe clear your browser cookie/cache/etc. to be safe, as well. That's how my friend got rid of that auto-post junk of her Tumblr account.
