I play a game in sl which has what we call "bases" in the game. For a base, you have to have land and rez them. There is a certain group within the game that we have recently found are using Abandoned Land owned by Linden Labs that still has rez on, and also using land owned by other residents who aren't on sl anymore. In my eyes this is the same as stealing. However, I was wondering what the LL view would be on this? I am assuming it would be something, that if reported, LL would not approve of, since if that was the case everybody would do it and nobody would ever pay for land they use. But I am curious, anyone know for sure? Figured I would ask before reporting it.
