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

MangaToken._writeCheckpoint(address,uint32,uint256,uint256) (contracts/MangaToken.sol#215-233) uses a dangerous strict equality:
- nCheckpoints > 0 && checkpoints[delegatee][nCheckpoints - 1].fromBlock == blockNumber (contracts/MangaToken.sol#225)
Don't use strict equality to determine if an account has enough Ether or tokens.

MangaToken.delegateBySig(address,uint256,uint256,uint8,bytes32,bytes32) (contracts/MangaToken.sol#81-122) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(now <= expiry,MangaToken::delegateBySig: signature expired) (contracts/MangaToken.sol#120)
Avoid relying on block.timestamp.
