Still trying to get in, including lowering my security and allowing cookies from the site. I keep getting blocks from my security, I guess.
"Hides its identity" alert at Aimoo
The assessment is based on geographical location and other factors such as site security, cookie handling, etc., etc., where CA servers run tests on sites and constantly update a list of URLs. Naturally as you get more visitors that report on your site, you may find that the security level changes. I would think that the fact 'the owner hides its identity' is a major contributary to the high risk status.
This found in the CA Website Inspector, CA Toolbar help.
Note: Many sites are considered high risk because the site owner's identity is hidden. In order to change their status, CA needs the name of the owner of the site, its location (city, state [when relevant] and country) and any form of proof that the owner exists in the claimed location and that he owns the site.
