Tried it on Chrome right now, I got the phishing detected warning: “Suspected phishing site!” so it should be ok now.
After reblogging you a few minutes ago, I got this message from some unknown user:
have you figured out how to fix that untitled problem with your blog cause im having the same problem
This guy’s blog was also redirecting to tumblrlogin.
I see a suspended page for tumblrogin. Did you clear your cache?
I contacted Hostgator, and it seems that the domain name is pointing to oversee.net right now.
Tumblrlogin [dot] com is again active.
From what I gather it is just one person behind it or at least just one group of people. All of the domains I have seen are interconnected in various ways.
Tumblr we can defeat this one person. We out number him.
Known domains: tumblrlogin (dot) com, tumblrsecurity (dot) com, tumblriq (dot) com
