Killer's server is full of edgy kids that are mostly super admins. One of the SAs banned an admin permanently without any reason. The host took away the super admin but it still was still auto. Don't give people power if you can't handle it either.
Tip: Don't admin friends just because they are your friend
Don't admin anyone just because they threaten you
Don't admin anyone that helps a lot, that does not determine if they are good at taking care of people/server
This is the obvious for tips but just leaving it there
