simple:
1. get the script_terrain build(you have to build in a 64x64)
2. get the moderator add-on, which adds moderators, who can kick people, but cannot ban them
3. get a whole lotta admins(hardest part right there)
4 get clear spam bricks(pretty obvious)
its just people make freebuilds without planning it out, and thus, people take advantage of it
