Many of the sites are also listed in the BEA FAQ sticky.
Just a side about searches, there is a site called
www.scandoo.com that screens Google, MSN, and Yahoo searches. It "rates" the resulting sites as being safe, unsafe, or unknown. This is very helpful since porn, spam, and spyware sites regularly show up even when searching for innocent words or phrases.
Us "professionals" may not see the need for something like this, but think of your kids and grandkids that are online doing research for school work, or just playing around. Or for other novices, like my sister, who are constantly unknowingly downloading crap on their computers and frying their hard drive. If they know not to click on the site with the red X, it will stop them from going into some innocent sounding porn site, or one that will download a virus on your computer. No matter what antivirus or spyware protection you use, these scumbags are always one step ahead.
