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

Tue Feb 21 23:24:02 UTC 2012

I'm probably asking for trouble posting to the whole wide listserv, but..
 I'm philosophically opposed to turning off public build unless it's truly
necessary.

To me, the most important and magical aspect of the SL and Opensim
platforms is the ability to collaboratively create user generated content
and _to invite others to do the same_.  The possibility for a visitor to
leave something creative for others to see or use (stigmergy
http://en.wikipedia.org/wiki/Stigmergy) is what sets these platforms apart
from others.  I like discovering what users leave behind and 99% of the
time it is not griefing activity at all.

And before you say you're shocked and how that never works, we have a
multi-sim mainland community in Second Life that has had public build
turned on for going on 6 years.  It just requires a little extra effort to
keep things tidy, and the benefits have far outweighed the risk/work
required to keep the tiny minority of jerks at bay.  Visitors can always
open packages and play with the things they discover in our space, and they
can share things with the community or even add to it - we just reserve
editorial rights of course.  hehe.

In any case, the fault was really mine for not checking my sims
periodically, and that was the reminder I wanted to share (and a little
grouching about the griefer).   But considering FleepGrid has been up for
over a year and a half and in that time people have left gifts, funny joke
items, shared freebies, and opened lots of boxes but this is the first
griefing activity I've seen..  I think that's a good argument for leaving
public build on - you might be surprised at the nice things you find.  ;)
 (So long as you clean up periodically!)
