I am trying to block tumblr, and all it's pages, using my hosts file. Usually I would just add an entry like
127.0.0.1 tumblr.com
to my file, but tumblr has websites in the format " sitename.tumblr.com"
I have tried
127.0.0.1 *.tumblr.com
127.0.0.1 http://*.tumbr.com
And neither work either. Does anyone know how to block tumblr without installing bulky software?
