How it works

Outfoxed reads and publishes trust assessments as RSS, with a few extra tags. Such a file might say (translated into English) that xyz.com is good, while zyx.com is bad, and xxx.com is dangerous. But the key to everything is that these RSS files can talk about other RSS files. So one file may say that the file at xyz.com/mary.xml contains trustworthy information, while the file at abc.com/bob.xml should be ignored.
Just like a normal RSS reader, Outfoxed periodically downloads these files from the web, and keeps a local database of all reports.
