I found a security breach in instawallet last week...  I fixed it for them... they never tipped me or anything...

However the bug I found only impacted about 3000 of their clients and roughly 100 bitcoins max,  what's showing up on that screen is something bigger (at least big enough to shut down the whole freaking site)  and most likely unrelated,  because mine was just that Google was listing people's wallets....  and they banned it in Google Webmaster tools, so that issue is resolved...   that notice though is all sorts of red flags..
