A webmaster brought to my attention some months ago that one of my sites was coming up with warnings in site advisor because i was linking to nastydollars.com (which site advisor warns of because of pop-ups or exit consoles). The particular link hadn't been converting for me anyway so as a test I took it down, and contacted site advisor asking them to re-test my site. They got back to me and said it would be scanned again in a few weeks. That was months ago and still nothing.
The worst part is that some webmasters trust site advisor like it's the gospel and will delete trades based on its results. For example, some well known freehosts come up with warnings, and not because of any general pop-ups or redirects from the owners themselves, but because a particular subdomain/account on the free host has been scanned at some point, where some cheater is doing some fucked up things with his account.
I just think in some cases a little bit of investigating will show that a site advisor warning is not a major concern
