hughperkins was using a "security mindset", and was implying that the site, due to lack of authentication, was being tricked into showing "George Soros" as a supporter because it just let anybody type in "George Soros".
This is not the case. The page of supporters is a page they designed, with no user input. The site is making the explicit claim that George Soros, that George Soros, is a supporter.
If you believe the site is lying, no amount of authentication on the site's side is going to fix that!
