I am always amused by the amount of people using tools to protect their property
I use teh LL simple ways... return object 3 mins, options, only people in my group can rez, fly, build, object entry, run scripts, safe mode, no push, and avatar on other parcels cannot see and chat with avatar on this parcel, restrict voice to parcel, sounds and avatar sound set to restrict gestures to this parcel.
this way people dont annoye me, cannot cam in, and I dont have to listen or see my neighbours, land is public they can walk over and chat (some neightbours are nice I dont mind them but nothign stays on the property.
I dont get the point of having some attack dog, sheep, bees etc to annoye someone on your land, I think if your so worried about it, then set up ban lines on, and that way you wont have issues.
I like when people walk over and see the constructed house or how I setup the LL house to a dj studio and get ideas to build stuff for themselves, secondlife is about sharing the experiences isnt it ?
