I don't really think siteadvisor really cares. I have yet seen site advisor reversing a red flagged sites back to green. I have seen a few sites that were label red with a few ppl leave a positive comments but site advisor don't reverse the decision even after the site have make modification and remove the offending link. It's easier to get red flagged but its hard to get them to review back your site and reverse the decision unless of course I guess you can always pay them.
