How to block someone on Tumblr?

[Mandy]

Some weirdo keeps sending me creepy messages on Tumblr. When I went to his blog, it was full of pictures of naked women! I've gotten 3 messages from this creep in the past two days. I never reply. How can I block him?

you can't block people, however you can "ignore" them, which is pretty much the same thing;
-They will not be able to see your posts on their Dashboard.
-You won’t see them listed in post notes or Dashboard notifications.
-You will also not receive any messages from them.

type the guy's username into here: http://www.tumblr.com/ignore
