SQUID [Squid Game] Token (2)

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

Contract creator or owner is blacklisted for past scams

Contract locking ether found:
Contract SQUID (#214-253) has payable functions:
- ApprovedEngine.constructor(address) (#182-185)
- Engine.fallback() (#145-147)
- Engine.receive() (#149-151)
- SQUID.constructor(address,address) (#215-226)
But does not have a function to withdraw the ether
Remove the payable attribute or add a withdraw function.

Token is flagged by TokenSniffer (admin)

Contract ownership is not renounced (belongs to a wallet)

SQUID.constructor(address,address)._sir (#217) shadows:
- SQUID._sir() (#242-247) (function)
