We'd like to caution our Second Life readers about a dodgy Second Life viewer that's currently doing the rounds under rather dubious circumstances. The viewer is calling itself Neil Life, and purports to include some content-ripping features over and above those normally available to users.
One particular feature of the viewer, apparently related to a permissions exploit, appears to have triggered Linden Lab to perform an emergency update to Second Life to close the exploit last week.
The viewer was widely advertised last week with distributed notecard advertisements in-world which purported to have been created by famed resident, Gwyneth Llewelyn. In actual fact, a copy of one of her existing notecards had simply had the text replaced so that it appeared that she had authored it.
(This is one of the main reasons we don't generally accept the provenance of notecards in Second Life)
