The bottom line is that this is a big security hole, and it's easy to exploit. The guy that put up the original site didn't do anything illegal as far as I can tell (he has not been arrested or charged with a crime), it's just a case of the authorities being made to look like fools and trying to harass him as punishment.
Other sites will keep popping up to do just this, some will be overseas and the US govmt will not be able to get them taken down.
When will they learn to stop blaming the messenger and address the issue?? It's like MS trying to sue people who uncover flaws -- don't blame the messenger, fix the damn hole.
