Search engine

Hi. My question is about the site contents from DirectFileAccess (http://www.directfileaccess.com).

While I was browsing the web, I noticed many files I needed could be found in www.directfileaccess.com, so I joined up — BIG MISTAKE I think…Once I became the member, I could no longer find ANY of files I was looking for from their search engine. Maybe I am doing something incorrectly but most of files I am looking for disappears (comes with “oops no match msg) after I log-in and do search (for example before I log in — using the site’s own search engine, I can find at least 10 files for a keyword like C&C, but once I log in and use the very same search engine, I can’t find ANY with the very same keyword). I think those popular files shows up only when you are unregistered or not logged in as a bait to lure idiots like me to join their sites…T.T I dont think their site is even legal…

Am I doing something incorrectly or they are frauds?
