I've found 2 problems I think Badspot may want fixed, so I'm telling him about them jsut incase he doesn't know:
1)If someone you put under trust builds then you build ontop and they clear their bricks using commandtoserver('clearbricks'); (/clearbricks), then your bricks will be floating.
2)It seems Badspot put the trust check AFTER the planting of bricks. People can put a ghost infront of a door and keep hitting plant really fast to make a wall that people would atleast get stuck in. Packer saw, I showed him in his server.
