Cyber Bullying

We all know it exists in one form or another. But what can be done to stop it?
I recently got myself in the habit of watching the evening news online from the Maritime news centre since I no longer have cable and am curious of what is happening in my area.
There was a segment on cyber bullying covered tonight. The headline actually caught my eye because it said "Anti-bullying advocates fuming over "dirty" website". My first thought was that the news was somehow clued into the website that I witnessed a lot of cyber bullying taking place. But in fact, it was mentioning a site which might be much worse.
I think of it as a real life gossip girl. A man owns a site called "The Dirty" in which people can submit photos and blasts of other people they may know. Most of the girls in the photos dress provacatively, but is that a reason for their names to be slandered across the internet? No. Some may have had children at an early age. Or may have done drugs. Or have family drama going on. But that's still no reason to spread it across the internet. That's their business and they should deal with it themselves.
It disgusts me that this is going on.
How can we protect ourselves and others from this happening? I don't think we can, as sad as that may be.
Do you have any solutions?
