Who is the Sauron of Second Life?

Just to confirm that Travolution had nothing to with the attack on Second Life over the weekend by a mystery worm, known as Grey Goo! [Us amateurs are often accused of all sorts in SL!]

Seriously: the attack apparently came in the form of spinning gold rings planted in various around Linden, which sent the system into a spin when residents tried to interact with them.

The Lord of the Rings - pun most defintely intended - has yet to be identified.
