I found two advertisers (perhaps 3) that are
trying to sneak in the installation of software.
I asked to stop displaying those advertisers
on the site.

But you have to understand that most advertising 
companies are just linking to other ones when they 
don't have enough ads to display. So it's hard to 
track down from where an ads really come as there 
may be several layers. (And as I said, I still use 
my old Netscape 4.7 and I never saw a single of 
those ads. In fact, I nearly never ever saw a up)
