This is just something I've kind of always wondered. In Fort Wars, Freebuilds, and other kinds of server, I keep seeing people put quite a bit of effort into a build of some sort only to clear their own bricks and then leave. Why do people do this?
Is it because people are afraid their work will be saved and stolen? And if they're just going to clear their bricks anyways, why not just build in single player? It just doesn't make sense to me to contribute to a server or build and then just delete it all and leave, and I've never really remembered to ask anybody about it until recently.
