Unable to find manual contract audit (e.g. Certik, PeckShield, Solidity...)

Contract locking ether found:
Contract Token9CC1 (#1147-1760) has payable functions:
- Token9CC1.receive() (#1291-1293)
But does not have a function to withdraw the ether
Remove the payable attribute or add a withdraw function.
