I didn't realize google has gone this low. I went to google groups to look up some information on credit and finance and the first group i went to in the finance section displayed an adult ad, and it was a pretty bad one, like one you would see on a really bad porn site. I'm using firefox with adblock plus and my google preference is moderate safe search, which i thought would let google know i don't like seeing this sort of thing. You can tell clearly the adult ad is coming from google because if you move the mouse cursor over it , you can see the link as http://xxxxxx.googlegroups.com/web/....... What if it was some kid browsing these groups and google is displaying these ads to them.
