No one wants random people coming in.

- Picking up all the spare tools, resources etc (and then potentially logging off)
- Proceed to dismantle the main base
- Dig random holes or 'cause land damage not easily repaired (adding long term lag)
- Wasting resources and dying with freshly crafting server-current-best and being unable to reacquire the items (water deaths, edge of world etc).

You are 100% better off attempting to form a group, join a guild, or if blessed with actual friends into gaming... sucker them into playing as well!
