How am I _operating_ it? I deployed a smart contract and walked away. If I don't leave myself a backdoor, there's literally nothing I can do to prevent anyone in the world from interacting with the contract. Everyone that runs an Ethereum full node; they're the ones operating the laundering service. They run servers that store all the transaction records on their hard drives and do the processing of the ZK proofs allowing funds to be redeemed. Those are the people you have to stop if you want the service to go away. In this scenario, I as the contract deployer can do nothing whatsoever to stop them.
