Because it is a list of links to websites and paypal donate buttons, I don't think you can get ripped off using this site (Unless of course it is stealing your login info....oy vey). The site also includes a running list of stories on the Madoff case, you can find more information on ripped-off entities here, and my twitter feed contains a lot of news as it happened.
It is a great idea, I hope it is legit. It was also put together fast - the Madoff scandal only came to light @ 10 days ago. Of course, two books on the debacle have already been commissioned so "rapid*" is in the eyes of the beholder.
