[K12OSN] Way to block spyware with content filter?

I think it's a great idea.  
There are also sites that make custom hosts files to block bad sites
for windows that include all the advertising companies, along with
spyware sites.
Here is a sample hosts file that is filled with goodies.
It comes from this article.

Also you could possibly include some sites or regular expressions from
"adblock" lists that are used in firefox's adblock extension.

Here is their list, and you can even tweak it before downloading the file.

Thanks for sparking a great idea Jimmy!
