You sample randomly to discourage cheating. not because they think those people are cheating, but to make the risk higher of being caught if you do.
A simple example is a cashier asking you to open your backpack if you took it with you in their store. They don't think you stole anything. They ask it to make sure people who intend to steal are discouraged to come into that store and fill their backpacks
As setsul mentioned, exceptional treatment happening is like half the reason RGL threads are made. If he'd not have been banned for this, a thread might've been made of someone complaining admins are giving exceptions while their own teammates got banned for it
