It's a little hard to find specifics, but here's the gist: someone (a "griefer" or someone who had a bone to pick with Second Life) created a section of code (SL allows you to program effects or spawn objects by creating routines) that spawned a ring with a face in it. If anyone interacted with it in any way, it spawned more nearby. So basically what happened was this thing kept replicating out of control, which made it the equivalent, I suppose, of a denial of service attack on their servers. It caused a system rollback over the entirety of the virtual domain, because the rings were so pernicious. Everyone was complaining because they were losing merchandise or profits they had made.

PS Any word on when we'll be converting those stories? Did I miss the boat?
