Second Life Copybot

I've encountered a few people on SL who have been able to disable scripting in sandboxes. I was wondering if anyone here could tell me where to find something like that, or tell me how it's done so I can make it myself. Thanks!

if you own the sandbox then its done at region level

you can do that when you have your own land, its just open the land options, then disable scripts, you can set it also only on group
