[Opensim-users] What happens when you forget to check your sims..

Tue Feb 21 23:35:20 UTC 2012

I'm with Fleep here. While "griefing" is a nuisance, it's typically very  
easily remedied by either restarting the simulator, or - at worst -  
reverting to a previous backup. If anything, I'd encourage people to do  
regular backups and not neccessarily to rely on server-side restrictions  
that may or may not work, but will certainly make life harder for the  
wrong people. The griefers will find a way around them; for them it's a  
sport, and the harder the obstacle, the more determined they are to  
overcome it. I think OpenSim even has some kind of auto-backup feature  
lately that saves regions as OARs. (I'm using the old and dull MySQL dump  
that works just as well.)
