The requiresTrust() modifier is used on the strategy, vault and factory contracts to prevent unauthorised accounts from calling restricted functions. Once an account is considered trusted, they are allowed to add and remove accounts by calling setIsTrusted() as they see fit.
However, if any single account has its private keys compromised or decides to become malicious on their own, they can remove all other trusted accounts from the isTrusted mapping. As a result, they are effectively able to take over the trusted group that controls all restricted functions in the parent contract.
Consider utilising Rari Capitals updated Auth.sol contract found here. This updated contract gives the owner account authority over its underlying trusted accounts, preventing any single account from taking over the trusted group. The owner account should point to a multisig managed by the Sandclock team or by a community DAO.
