Is there anyway to ban Yahoo's IP, or internet presence from my computer? Being exasperated with dwindling options and Yahoo's insistence on being the persistent friend that you don't want in your life, I am open to completely banning them from my computer.
I don't use anything Yahoo. I have been using Tumblr for a couple of years now though. Do you think they are piggybacking some malware with Tumblr users?
