Seems that (if I understand the rumor correctly) it might've been the person + syncophants I wrote* about in a post way back in March who perpetrated the hack job and script theft this week as revenge against LL for his recent permanent banishment.

*March 27-05: "I was appalled at how horrid some of the people on the black buildings side were. I certainly wouldn't describe it all as mental illness, but there was a perverse and ugly way these people chose to conduct themselves that is not within the boundaries of normal, healthy mental processes. It makes me wonder if, speaking generally, there should be a clearinghouse of information or perhaps health-provider notification for people whose behaviour results in them being banned from online environments such as SL."
