report
Token seems to be (relatively) fine. It still become a scam, but probability is moderate.

ERC20Permit.permit(address,address,uint256,uint256,uint8,bytes32,bytes32) (@openzeppelin/contracts/token/ERC20/extensions/draft-ERC20Permit.sol#40-62) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(block.timestamp <= deadline,ERC20Permit: expired deadline) (@openzeppelin/contracts/token/ERC20/extensions/draft-ERC20Permit.sol#42)
Avoid relying on block.timestamp.
