Can anyone point me in the right direction as how to block sites in OS X? What's the equivalent of a HOSTS file on OS X? I just signed up to Rhapsody again and I found out that the site actually plays streams through Safari but I got PISSED off when I found out that I still have ads. Ridiculous. I canceled it immediately after, but I figure I might as well use it for the month I have it now. They are all coming from i.realone.com/ads, so I just want to block out that URL and see if that clears it up or not.
