How do you track an anonymous message on Tumblr after it's been posted?

[Megan]

I posted an anonymous message on my Tumblr and I'm curious as to who it was from. It's already published and answered, and I don't have any add-ons that could help. Is there any way to track who the message was from? Thanks!

Hi! The only way to track and see who the anonymous person is, is if you go to the option where you can block that user. After you block them, you go to your blocked list and there will be a username telling you who it was. You can always unblock them right after.
