Strangely, a story like this imo is scarier than UB and FTP in terms of regulation.

UB and FTP are strong arguments for regulation. Having Middle Eastern nationals installing trojans and moving money around via poker is a bad omen for international player pools. And even on a US only regulated site, is there a way to prevent this? I understand the key difference is a perpetrator would be open to prosecution, and that's big, but can any site ascertain that this couldn't happen on a regulated site? I don't have the technical expertise to comment, but I just don't like the feel of this story and I frankly would almost like to see it go away.
