With regards to your question. There is a way to send massive amounts of streamed fragmented files to your computer once a hacker has your ip address or is in control of your viewer. I think this is a common problem as Jessie has said because if it wasn't then people wouldn't be posting help questions on second life forums and i also think that Linden Labs needs to take second life greifing and hacking a lot more seriously. If it was you griefed or hacked wouldn't you want something done about it?
