I can see how you might think it's creepy, but I really just wanted a good way to display what team other people are playing on.
It doesn't affect you outside of the server and you're not able to build while playing so I figured I may as well make trust do something. I try to make it super obvious what it's for, if you try to remove the trust it explains what it's for. I also have a command that explains what it means for anyone who is confused.
LAN = Spectator
Build = Guard
I could make an option to turn it off but I figure once you understand what it means it's helpful.
