See also the following interesting paper;

Adverse Selection in Online "Trust" Authorities, an empirical look at the best-known certification authority, TRUSTe. I cross-reference TRUSTe's ratings with the findings of SiteAdvisor -- where robots check web site downloads for spyware, and submit single-use addresses into email forms to check for spam, among other automated and manual tests. Of course SiteAdvisor data isn't perfect either, but if SiteAdvisor says a site is bad news, while TRUSTe gives it a seal, most users are likely to side with SiteAdvisor.

key finding: Sites certified by TRUSTe are more than twice as likely to be untrustworthy as a random sampling of popular sites. The relative hazards of TRUSTe-certified sites hold even when analysis controls for site attributes and for site complexity.
