I totally fell for the cloned site, until I realized I couldn't see your trust ratings.
I have added this line to /etc/hoosts (with one o)
127.0.0.1 bitcointalk.to
Now my computer can't access that phishing site anymore.
That is an excellent idea.
Someone who has time should maintain a list of these phishing sites, and we can encourage all new users to update their hosts file.
