One reason I do not like public servers.Yeah its a real problem. I want to play with other people, but I don't want the eventual instability that usually arises after a while, resulting in loosing it all.
Worst thing was that the giant tree was just one "small" part of the build I have never really bothered to invest a lot on a server since. Or at least not intended to.
Small or private servers are usually good because tighter community( and staff!) plus less banned items
