Who will fight the loshon hora?

I don't use the internet too often. I'm supposed to be in kollel full time. But bein hazmanim I work in an office and sometimes have to research names of rabbis worldwide on the internet. What freezes my blood is that upon typing in such innocent phrases as "Anycity Beis Din" into Google to find a phone number, I come across websites and blogs devoted to loshon hora as top links. How can we fight it? How can we get the word out: "This is assur" ?? People can mean well, I really believe that many do, but they don't understand that there is no heter for what they're doing. I was just so disturbed by this today that I had to post, although I haven't updated this blog regularly for years.
