Nope. He was snitched out by underlings, and his competitors through an anonymous internet mechanism. He was not caught out by official peer review until the peers could no longer avoid acknowledging their malpractice.
Interestingly, Korea is the best-wired country in the world, and is now suffering some pathologies from that which we might do well on Fr to pay attn to. In Korea, you use an official ID # (similar to our SS) for many commercial transactions. Chinese hackers recently got ahold of a quarter million of these #'s and joined online games in order to "farm" virtual merchandise (virtual swords and sorceries to be sold on places like ebay.) Big lawsuit time, for SK is highly litigious.

Interesting. Definitely a major scandal. I hope those involved get what's coming to them. In any case, science does eventually work, it sometimes takes a while, though, unfortunately. (Someone definitely would smell a rat if the results couldn't eventually be duplicated, though not until millions of dollars were wasted.)
